How many valence electrons does serine have?

Serine has five valence electrons. It has three valence electrons from the oxygen atom and one valence electron each from the carbon and nitrogen atoms in its structure.


How many electrons are in a completed valence shell of most second period atoms when they combine with other atoms to become molecules- 2 or 4 or 6 or 8?

The first two elements in the 2nd period are metals, and form ionic compounds rather than molecules. Boron, carbon, nitrogen, oxygen, and fluorine share electrons, forming covalent bonds with other nonmetals so that they will each have a full valence shell with eight electrons. The noble gas neon already has eight valence electrons and is generally nonreactive.
