Question

Which response includes all the following that are properties of most metals, and no other properties?

Z1) They tend to form cations.
Z2) They have high first ionization energies.
Z3) They have outer electronic shells that are more than half-filled.
Z4) They tend to form ionic compounds when they combine with the elements Group VIIA.

1. Z3 and Z4 only
2. Z2, Z3, and Z4 only
3. Z1, Z2, and Z3 only
4. Z1 and Z4 only
5. Z1 and Z3 only

Answer 1

Answer:Z1 and Z4 only

Step-by-step explanation:

One general property of all metals is that they form positive ions (cations) by electron loss. Secondly, elements of group VIIA have high electron affinities hence they easily accept electrons to form negative ions. The bonding between metals and elements in this group is almost always ionic in nature.
