Question

Responses

electronegativity and period
electronegativity and period

valence electrons and group
valence electrons and group

group and period
group and period

valence electrons and electronegativity

Answer 1

The correct response is:

valence electrons and group

Valence electrons determine how an element reacts chemically, and elements that are in the same group (or column) of the periodic table tend to have similar reactivities due to having the same number of valence electrons.
