    The modern Periodic Table is arranged by

    • Atomic number

    • Atomic mass

    • Atomic symbol

    Correct Answer
    A. Atomic number
    Explanation
    The modern Periodic Table is arranged by atomic number. This is because the atomic number of an element represents the number of protons in the nucleus of an atom. The elements are arranged in increasing order of atomic number from left to right and top to bottom. This arrangement allows for elements with similar properties to be grouped together in the same column, known as a group or family. It also helps to identify trends and patterns in the properties of elements as you move across a period or down a group.

    In 1913, an English chemist Henry Moseley decided to order the elements by their atomic numbers. 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Henry Moseley, an English chemist, indeed decided to order the elements by their atomic numbers in 1913. This decision was a significant contribution to the development of the periodic table as it provided a more accurate and logical way to organize the elements based on their fundamental properties. By arranging the elements in this manner, Moseley was able to establish a clear pattern and better understand the relationships between different elements.

    Johann Wolfgang Döbereiner

    • Came up with the idea - Law of Triads

    • Arranged the table by mass

    • Father of the Modern Periodic Table

    Correct Answer
    A. Came up with the idea - Law of Triads
    Explanation
    Johann Wolfgang Döbereiner is credited with coming up with the idea of the Law of Triads. This law states that when elements are arranged in groups of three, the middle element has properties that are an average of the other two elements. This idea was an early attempt to organize elements based on their properties and laid the foundation for the development of the modern periodic table.

    The Periodic Table is made of what kind of elements? (click all that apply)

    • Metals

    • Non-metals

    • Metalliods

    • Compounds

    Correct Answer(s)
    A. Metals
    A. Non-metals
    A. Metalliods
    Explanation
    The Periodic Table is made up of metals, non-metals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Non-metals, on the other hand, are usually dull, brittle, and poor conductors of heat and electricity. Metalloids have properties that are in between those of metals and non-metals. Compounds, on the other hand, are not elements but rather combinations of different elements. Therefore, compounds are not part of the Periodic Table.

    What is Moseley's Periodic Law?

    • Both physical/chemical properties of an element will appear periodically when arranged by atomic number

    • Triads appear in groups of 3

    • Elements have different atomic numbers

    Correct Answer
    A. Both physical/chemical properties of an element will appear periodically when arranged by atomic number
    Explanation
    Moseley's Periodic Law states that when elements are arranged in order of increasing atomic number, their physical and chemical properties show a periodic pattern. This means that elements with similar properties will appear at regular intervals in the periodic table. The law also emphasizes the importance of organizing elements based on their atomic number, rather than their atomic mass or other factors. By following this law, scientists can better understand and predict the properties of elements based on their position in the periodic table.

    How did Mendeleev arrange his Periodic Table?

    • Atomic number

    • Atomic mass

    • Atomic symbol

    Correct Answer
    A. Atomic mass
    Explanation
    Mendeleev arranged his Periodic Table based on atomic mass. He organized the elements in increasing order of their atomic masses, placing elements with similar properties in the same groups or columns. This arrangement allowed him to identify patterns and trends in the properties of elements, and also to predict the existence and properties of yet undiscovered elements.

    Henry Moseley biggest contribution to the Periodic Table is

    • Found the relationship between protons and the atomic number

    • Left blank spaces on the table for missing elements

    • Arranged the first Periodic Table

    Correct Answer
    A. Found the relationship between protons and the atomic number
    Explanation
    Henry Moseley's biggest contribution to the Periodic Table is finding the relationship between protons and the atomic number. This discovery led to the understanding that the atomic number, which is equal to the number of protons in an atom, determines the element's properties and its position on the Periodic Table. Moseley's work provided a more accurate and systematic arrangement of elements based on their atomic numbers, which is now the standard method used in organizing the elements.

    Antoine Lavoisier is the Father of __________.

    Correct Answer
    chemistry
    Explanation
    Antoine Lavoisier is widely recognized as the Father of Chemistry due to his significant contributions to the field. He is known for his meticulous experiments and his discovery of the role of oxygen in combustion. Lavoisier also developed the law of conservation of mass and introduced a standardized system of chemical nomenclature. His work laid the foundation for modern chemistry and revolutionized the understanding of chemical reactions and elements.

    The modern periodic table is arranged by _______  __________.

    Correct Answer
    atomic number
    Explanation
    The modern periodic table is arranged by atomic number. This means that the elements are ordered based on the number of protons in their atomic nucleus. The atomic number is a unique identifier for each element and determines its position in the periodic table. This arrangement allows for the elements to be organized in a logical and systematic manner, with similar properties grouped together in the same columns or groups. It also helps in predicting the behavior and characteristics of elements based on their position in the table.

    The "Law of ______", proposed by Johann Doebereiner, was an early attempt to classify elements by their relative mass and common properties.

    Correct Answer
    Triads
    Explanation
    The "Law of Triads," proposed by Johann Doebereiner, was an early attempt to classify elements by their relative mass and common properties. This law suggested that certain groups of three elements exhibited similar chemical properties and had atomic masses that were approximately in the middle and at the average of the other two elements in the triad. This concept helped in organizing the elements and understanding their patterns and relationships.

    (click all that apply) Dimitri Mendeleev's greatest contribution to the Periodic Table is ....  

    • Predicted properties of undiscovered elements

    • Left blank spaces for undiscovered elements

    • Discovered protons

    Correct Answer(s)
    A. Predicted properties of undiscovered elements
    A. Left blank spaces for undiscovered elements
    Explanation
    Dimitri Mendeleev's greatest contribution to the Periodic Table is his prediction of the properties of undiscovered elements and his decision to leave blank spaces for these elements. This allowed for the organization and arrangement of elements in a logical and systematic manner, providing a framework for future discoveries and advancements in the field of chemistry.

    The Modern Periodic Table is arranged (click all that apply)

    • Vertically by properties

    • Horizontally by properties

    • Horizontally by the number of protons

    • Vertically by the number of protons

    Correct Answer(s)
    A. Vertically by properties
    A. Horizontally by the number of protons
    Explanation
    The Modern Periodic Table is arranged vertically by properties because elements in the same group have similar chemical properties. It is also arranged horizontally by the number of protons, which is known as the atomic number. This arrangement allows for the elements to be organized in a way that reflects their chemical behavior and helps in predicting their properties based on their position in the table.

    What means repeating predictable patterns?

    Correct Answer(s)
    periodicity
    Explanation
    Periodicity refers to the occurrence or repetition of predictable patterns. It implies that certain events or phenomena happen at regular intervals or follow a consistent sequence. This concept is commonly used in various fields such as mathematics, physics, chemistry, and biology to describe cyclic or recurring patterns. Periodicity helps in understanding and predicting the behavior of systems or processes that exhibit regular repetition.
