At least one, and usually all, of the valence electrons of the metal atom is donated to the valence shell of the nonmetal atom.
One
All the elements with more than 4 electrons in the valence shell,which are usually gaining electrons and are reduced in the chemical reactions are named "non-metal".This does not include elements in transition metal
The transition metals.
Calcium is a metal that has two valence electrons.
N and V have same number of valence electrons.The number of valence electrons is 5. V is a metal while N is a non metal.
halogen NOTE added by Dr.J.): A halogen doesn't have a few valence electrons. They have 7 valence electrons.
The most reactive elements have either 1 valence electron or 7 valence electrons
