what are valence electrons of an atom?
12059
In 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.

Atoms of elements in this group have four valence electrons.

The valence electrons are in the outer shell of atoms which makes them available to form bonds with other atoms. The valence electrons are responsible for forming the bonds to other atoms as compounds are formed or later additions or rearrangements are made to existing molecules.

Valence electrons can be found by determining the electronic configurations of elements. Thereafter the number of electrons in the outermost shell gives the total number of valence electrons in that element.

The valence electrons are involved in bonding one atom to another. The attraction of each atom's nucleus for the valence electrons of the other atom pulls the atoms together. The electrons on the outermost energy level of the atom are called valence electrons.

Sodium has one valence electron. Valence electrons are electrons found in the outermost shell of an atom. The shell number representing the valence shell will differ depending on the atom in question. For sodium, which is in the 3rd row of the periodic table, the valence electrons will be found in the 3rd shell.
