Answer:
(b) lose electrons and form positive ions
Explanation:
<u>Ionic bonding:-
</u>
This type of bonding is formed when there is a complete transfer of electrons from one element to another element. In this bonding one element is always a metal and another is a non-metal.
<u>For example, the formation of NaCl</u>
The electronic configuration of sodium with Z = 11 is : 2, 8, 1
The electronic configuration of chlorine with Z = 17 is : 2, 8, 7
<u>Thus, sodium loses one electron and become positively charged and chlorine accepts this electron and become negatively charged and they have both their octets complete and form ionic bond.</u>
Hence, can be seen from the above example, metallic atoms generally lose electrons and form positive ions.
