Sulfur (s) is in group 16 of the periodic table. how many valence electrons dos an atom of sulfur have?

6 because the number of valence electrons is always the ones-place of any two-digit group number. So an element in group 18 would have 8 valence electrons
Hope this helps!

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.

Hope it helps :) ps have a great day!!(taken from Google)
