S is in Group VI. This means that it has 6 valence electrons.
I hope this helps :)
At first sight it doesn't bode well. The key is in how firmly the protons and neutrons are held together. In the event that an atomic response produces cores that are more firmly bound than the firsts then vitality will be created, if not you should place vitality into make the response happen.
This is true. Because without the 3 you would need to take it out from the equation
Protons and neutrons make up most of an atom's mass. Electrons have almost no mass.
