How many valence electrons are in atom of sulfur?

Sulfur has six .

Valence are the outermost electrons which therefore are located on the highest energy levels. Consequently, these are the electrons available for chemical .

To determine the valence number, look at electron configurations which denote the number of electrons in the different energy levels and orbitals.

Neutral sulfur has 16 electrons because it's is 16.

The in ##1s^2 2s^2 2p^6 3s^2 3p^4##

What does this configuration tell us?

Sulfur has two electrons in the 1s orbital, two electrons in the 2s orbital, and 6 electrons in the 2 p orbitals. The electrons are part of the first and second energy levels, the electron core.

The next energy level, the last one, is the outermost energy which comprises the valence shell. There are 2 electrons in the 3s orbital and 4 electrons in the 3 p orbitals. Add the electrons to these last types of orbitals and you have the number of .
