-Bonds are formed- When atoms collide, they may form bonds with one another. This happens when the electrons in the outermost energy level of each atom interact and form a shared pair of electrons. The shared electrons hold the atoms together in a chemical bond.

The reactants gain mass

A chemical reaction involves the rearrangement of atoms. When the atoms are rearranged, they form new bonds with one another. As a result, the overall mass of the reactants increases.

And Aton loses a proton from its nucleus

In some reactions, an atom may lose a proton from its nucleus. This can happen when the atom reacts with another atom that has a stronger affinity for the proton.

A neutron is converted into a proton

In some reactions, a neutron may be converted into a proton. This can happen when the neutron reacts with another particle that has a higher energy than the neutron.

A proton is added to the nucleus of a atom

In some reactions, a proton may be added to the nucleus of an atom. This can happen when the atom reacts with another atom that has a weaker affinity for the proton.

An atom acquired an electron lone pair

In some reactions, an atom may acquire an electron lone pair. This can happen when the atom reacts with another atom that has a higher energy than the atom.

The products have less mass than the reactants

In some reactions, the products have less mass than the reactants. This can happen when the atoms in the reactants are rearranged to form new bonds with one another.
