How many valence electrons does oxygen have?

Oxygen has 6 .

A way to remember this is to note that it is in column 16 of . For the representative (columns 1, 2, 13-18), the digit in the units place of the column number is the same as the number of . Elements in column 1 have one valence electrons, elements in column 13 have 3 valence electrons, etc.

The 2 electrons on the top represent the ##s^2## and the four other electrons represent the ##p^4##.
