When a gamma ray is emitted from the nucleus of an atom: it reduces the overall energy of the nucleus it increases the overall energy of the nucleus it causes a charge imbalance in the nucleus it causes changes in the electronic structure outside of the nucleus?

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
