Question

what is valence electron,?​

Answer 1

Answer:

chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Answer 2

The outermost electron shell of an atom is called valence shell. The electrons present in outermost shell of an atom are called as valence electrons. The valence electron of an atom take part in a chemical reaction because they have more energy than all the inner electrons.
