Most chemical reactions involve the breaking and formation of chemical bonds. It takes energy to break a chemical bond but energy is released when chemical bonds are formed. If more energy is released than consumed, then the chemical reaction evolves heat and is said to be exothermic.

Explain, in terms of subatomic particles, why atoms of H-1, H-2, and H-3 are each electrically neutral.

jasenka [17]

The atoms are all electrically neutral because the number of protons is equal to the number of electrons.

<h3>What is electrical neutrality?</h3>

An atom is electrically neutral when the number of protons is equal to the number of electrons.

In the cases of H-1, H-2, and H-3, the nuclides have one electron an one proton. The different mass numbers arise from differences in the number of neutrons. Hence in all cases, the nuclides are electrically neutral.
