The mass number tells the number of protons.
Explanation:
Elements are composed of tiny particles called Atoms. Atoms of any one element are different from those of any other element. Atoms of different elements can form compounds by combining in whole-number ratios. Chemical reactions occur when atoms are combined together by chemical bonding to form chemical compounds.
