In exothermic reactions, the system in energy.

releases, increase

Explanation:

The total energy of products in an Exothermic reaction is less compare to

total energy of the reactants. As a result of these the enthalpy becomes negative, then there is release of heat to the surroundings, which increase the energy of the immediate surroundings inform of heat. Hence the system release energy while the surroundings energy increase.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

you need to have a picture of the atom that way we can answer it
