Explanation:
During a chemical reaction, the atoms of the original substances gain, lose or share their electrons with those of the substances with which they are reacting. The reaction creates new substances made up of a new combination of atoms and a different configuration of electrons.
1,500,000,000,000,000,000,000
or 1.5e+26
An atom contains protons, neutrons and electrons.
Protons have a positive charge (+1).
Neutrons have no charge (0)
Electrons have a negative charge (-1)
The number of protons and electrons is always the same and so the charges add up to make 0. Therefore there is no overall charge on atoms.
