Who is the creator of the periodic table?
- A.
Dimitri Mendeleev
- B.
Henry Moseley
Correct Answer
A. Dimitri MendeleevExplanation
Dimitri Mendeleev is credited as the creator of the periodic table. He developed the table in the late 19th century and organized the elements based on their atomic mass and properties. Mendeleev's periodic table provided a systematic way of organizing the elements and predicting the properties of undiscovered elements. His work laid the foundation for the modern periodic table that we use today.Rate this question:

_______________discovered the number of protons in the nucleus of each atom.
Correct Answer
Henry MoseleyExplanation
Henry Moseley discovered the number of protons in the nucleus of each atom. This discovery was made through his experiments with X-ray spectroscopy. Moseley observed that the X-ray spectra of different elements shifted in a predictable pattern when the elements were arranged in order of increasing atomic number. He realized that this shift was due to the number of protons in the nucleus, which determined the element's atomic number. Moseley's work provided a more accurate and systematic way of organizing the elements on the periodic table, based on their atomic numbers rather than their atomic weights.Rate this question:

The element germanium is in what element group?
- A.
Basic Metal
- B.
Non-Metal
- C.
Rare Earth
- D.
Semi-Metal
Correct Answer
D. Semi-MetalExplanation
Germanium is classified as a semi-metal because it exhibits properties of both metals and non-metals. It has a metallic appearance and is a good conductor of electricity, similar to metals. However, it also has some non-metallic properties, such as being brittle and having a lower melting point than most metals. Therefore, it falls into the semi-metal group, which is a category of elements that have characteristics of both metals and non-metals.Rate this question:

The element Rubidium is in what element group?
- A.
Alkaline earth
- B.
Basic metal
- C.
Alkali metal
- D.
Transition metal
Correct Answer
C. Alkali metalExplanation
Rubidium belongs to the alkali metal group. Alkali metals are highly reactive and have only one electron in their outermost shell, which they readily lose to form positive ions. Rubidium, with atomic number 37, falls into this category as it exhibits similar properties to other alkali metals such as lithium, sodium, and potassium. These elements are soft, silvery-white metals that react vigorously with water and have low melting and boiling points. Therefore, Rubidium is correctly classified as an alkali metal.Rate this question:
