Question

When a new bond forms in a chemical reaction, what happens?

Answer 1

The answer to this question would be A. Energy is released. 

When a chemical bond is a form, the bond will either suck up energy or produce energy. So, to be precise the energy is not always released but also can be absorbed. In this case, the energy released number will be a minus.

Options B and C is definitely wrong since the bond is formed by an electron, it won't affects neutron/proton.
Option D might be true since the product is made of 2 or more atoms then it would seem larger. But the size of the actual atom won't be increased.

Answer 2

ENERGY IS RELEASED IF NEW BONDS ARE FORMED.

Explanation:

When reactants consolidate in substance responses, the bonds between the reactants break by engrossing the vitality which is provided to the reactants at the hour of response and structures results of those reactants which discharge the vitality.

This response is called the exothermic response. When new bonds are formed, higher potential vitality level changes to the lower potential vitality levels. potential vitality is changed over into motor vitality when the bonds break and new bonds are shaped.
