Concept introduction:
Atoms are the tiny particles made up of electrons, protons and neutrons. They cannot be seen with naked eyes.
Answer to Problem 1E
Atomic number represents the number of protons in nucleus of an atom and number of electrons in a neutral atom. It is identity of an atom.
Explanation of Solution
Atomic number is equal to the number of the protons in an atom and the number of protons are identify of an atom of element. No two elements can have same number of protons. In other words, it tells the number of protons in nucleus of an atom and number of electrons in neutral atom.
Atomic number represents the number of protons in nucleus and it is identity of an atom.
