1 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. 1234567891011121314151617181920 2122232425262728293031323334353637383940 41424344454647484950 1.I, II, and III 2.II and III 3.I and IV 4.II and IV 5.none of these answers
