The electron configuration for cobalt is:
[Ar] 3d7 4s2
Answer:
Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction.
Explanation:
Breaking chemical bonds absorbs energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
They have different number of Neutrons and protons, so their masses are different
