What is true about the element calcium Ca atomic number 20 A It has 2 valence electrons B It has 4 valence electrons C It is a nonmetal D It is reactive E It is metal?
E. It is metal. Calcium has 2 valence electrons and is classified as a metal. It is also reactive, especially with water and oxygen.
Why do most element have a characteristics valence?
Valency depends upon no of electrons in outer most shell the atoms have a specific no of electrons in valence shell so they have characteristic valence .(but transition metal violate this rule).
