How many outer-shell electrons does sulfur have
1. Sulfur has 6 outer-shell electrons. 2. It is not a stable shell. 3. 2 electrons are needed to make Sulfur’s shell stable. A stable shell has 8 electrons. It has 6 outer-shell electrons because it is in Group 6A on the Periodic Table. The outer shell electrons, or valence electrons, are the ones on the very outside of the electron. In order for a shell to be stable it should have 8. If it has just under 8 it is unstable and will react easily with other atoms in order to gain an extra electron or two so that it has a full set of 8 outer-shell electrons.
