How many valence electrons does sulfur possess? And how do we know?

Answer 1

S does have 6 valence electrons.

As a very general rule- this does not always work, but generally, it does- you can tell how many valence electrons an element has from its position on the periodic table. If you go left to right, counting the number of elements in the s and p blocks up to and including the element, that number is equal to its number of valence electrons.

For instance, fluorine has 7 valence electrons. If you count across the table, counting s and p block elements, you get 7. It has 7 valence electrons.

Sulfur possesses six valence electrons. This is determined by its position in Group 16 of the periodic table, indicating the number of valence electrons corresponds to its group number.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
