- 1.
What is an atom?
- A.
An atom is the smallest amount of a substance that we can have, that will still retain all the features of that substance.
- B.
It is what you are left with when everything else has been boiled away.
- C.
It is a really small piece of paper.
Correct Answer
A. An atom is the smallest amount of a substance that we can have, that will still retain all the features of that substance.Explanation
The correct answer is an atom is the smallest amount of a substance that we can have, that will still retain all the features of that substance. This answer accurately describes the concept of an atom as the fundamental unit of matter that retains the characteristics of a particular substance. It emphasizes that atoms are indivisible and cannot be broken down further without losing the properties of the substance they belong to.Rate this question:

What is a molecule?
- A.
It is when two or more atoms are present in the same place
- B.
It is two or more atoms that are chemically joined together, the atoms can be the same or different
- C.
It is when different coloured balls join together
Correct Answer
B. It is two or more atoms that are chemically joined together, the atoms can be the same or differentExplanation
A molecule is formed when two or more atoms chemically bond together. These atoms can be of the same element or different elements. The chemical bond between the atoms holds them together and gives the molecule its unique properties. This definition excludes the option of different colored balls joining together, as it does not involve chemical bonding between atoms.Rate this question:

This box contains:
- A.
Atoms of an element
- B.
A compound
- C.
Molecules of an element
Correct Answer
C. Molecules of an elementExplanation
The given answer, "Molecules of an element," is correct because molecules are formed when two or more atoms of the same element are chemically bonded together. In this case, the box contains molecules of an element, indicating that the atoms inside the box are bonded together to form a specific element. The other options, "Atoms of an element" and "A compound," are incorrect as they do not accurately describe the contents of the box.Rate this question:

This box contains:
- A.
Atoms of a compound
- B.
Atoms of an element
- C.
Atoms in a mixture
Correct Answer
B. Atoms of an elementExplanation
This box contains atoms of an element. An element is a substance that cannot be broken down into simpler substances by chemical means. Atoms are the basic building blocks of elements, and each element is made up of atoms of the same type. Therefore, if the box contains atoms of only one type, it must be atoms of an element.Rate this question:

What is an element?
- A.
An element has all the atoms packed closely together
- B.
An element contains only one type of atom
- C.
An element is what all substances are made from
Correct Answer
B. An element contains only one type of atomExplanation
An element contains only one type of atom. This means that all the atoms in an element have the same number of protons in their nucleus. Each element is unique and is represented by a specific symbol on the periodic table. This characteristic of having only one type of atom distinguishes elements from compounds, which are made up of different types of atoms bonded together.Rate this question:

This box contains:
- A.
A mixture of elements and compounds
- B.
Only compounds
- C.
Different atoms
Correct Answer
A. A mixture of elements and compoundsExplanation
The correct answer is "A mixture of elements and compounds" because the box contains both elements and compounds. A mixture is a combination of different substances that are not chemically bonded together, and in this case, the box contains a combination of elements (which are pure substances made up of only one type of atom) and compounds (which are substances made up of two or more different types of atoms chemically bonded together). Therefore, the box contains a mixture of both elements and compounds.Rate this question:

This box contains:
- A.
Many types of atoms
- B.
Molecules of a compound
- C.
Different types of compound
Correct Answer
B. Molecules of a compoundExplanation
The given answer suggests that the box contains molecules of a compound. This is because compounds are formed when two or more different types of atoms chemically combine together. These atoms bond together to form molecules, which are the smallest units of a compound. Therefore, the presence of different types of compounds in the box implies the presence of molecules of those compounds as well.Rate this question:

What is a mixture?
- A.
A mixture is a mix of atoms or molecules that are not chemically joined together and are easy to separate
- B.
A mixture is a collection of different atoms joined together
- C.
A mixture is any two different atoms
Correct Answer
A. A mixture is a mix of atoms or molecules that are not chemically joined together and are easy to separateExplanation
The correct answer explains that a mixture is a combination of atoms or molecules that are not chemically bonded and can be easily separated. This definition highlights the key characteristics of a mixture, emphasizing that its components retain their individual properties and can be physically separated from one another.Rate this question:

Elements are grouped together in the ................. table
Correct Answer
periodic
PeriodicExplanation
The correct answer for this question is "periodic" because elements are grouped together in the periodic table. The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties. It allows scientists to easily study and understand the properties and behavior of different elements.Rate this question:
- 10.
The periodic table is divided into
- A.
Elements and compounds
- B.
Metals and non-metals
- C.
Solids, liquids and gases
Correct Answer
B. Metals and non-metalsExplanation
The periodic table is divided into metals and non-metals based on their properties. Metals are typically shiny, malleable, and good conductors of heat and electricity. They are found on the left side and middle of the periodic table. Non-metals, on the other hand, are usually dull, brittle, and poor conductors of heat and electricity. They are located on the right side of the periodic table. This division helps in categorizing elements and understanding their characteristics and behavior.Rate this question:
