Which response includes all of the following that
are properties of most nonmetals, and no other
properties?I. Outer electronic shells contain
four or more electrons. II. They tend to form
positive ions. III. They are more likely to form
ionic compounds than covalent compounds when they
combine with other nonmetals. IV They have high
electronegativities.
