Answer:
hey mate
The outershell 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 are called to be as valence electron
The number of valence electrons of an element can be determined by the periodic table
Valence electrons are also responsible for the electrical conductivity of an element; as a result, an element may be classified as a metal, a nonmetal, or a semiconductor
