How do you think the number of valence electrons relates to an element's chemical properties?

Electrons in the outermost shell are called valence electrons, because it is their interactions that determine the chemical properties of an element. The columns that were set up to group elements by similar chemical properties turn out to be the exact same columns defined by the number of valence electrons.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
