Concept explainers
(a)
Interpretation:
Whether the statement “atoms are like small, hard sphere” is true or false is to be predicted. If it is false then the true statement is to be stated.
Concept introduction:
The universe is made up of number of materials that have different shapes, size, color and texture. The collective name given to the different materials is “matter”. Earlier according to philosophers, it was thought that every matter of this universe is made up of atom.
(b)
Interpretation:
Whether the statement “an atom is electrically neutral” is true or false is to be predicted. If it is false then the true statement is to be stated.

(c)
Interpretation:
Whether the statement “an atom consists mostly of empty space” is true or false is to be predicted. If it is false then the true statement is to be stated.

(d)
Interpretation:
Whether the statement “the subatomic particles of an atom are electrons, protons, and neutrons” is true or false is to be predicted. If it is false then the true statement is to be stated.
