Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent. However, polyploidy is found in some organisms and is especially common in plants.

In chemistry, 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. sorry for wrong ans

Valence electrons = A single electron or one of two or more electron in the outer shell of an atom that is responsible for the chemical properties of the atom. Valence shell = valence shell is the last shell occupied by electrons in an atom.
