What must occur before clouds can form?

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

: )

a redox reaction

explanation:

potassium metal is oxidized to potassium ion, and iodine is reduced to iodide ion, and we add (i) and (ii) together to eliminate the electrons.
