# When combining with nonmetallic atoms, metallic atoms generally will

$(a)\;\text{lose electrons and form negative ions} \\(b)\;\text{lose electrons and from positive ions} \\(c)\;\text{gain electrons and from negative ions} \\ (d)\;\text{gain electrons and form positive ions}$

Metals tend to lose electrons and form positive ions.
A neutral atom of Li has 3 protons (+) and 3 electrons (-).
If it loses an electron, the Li atom now has +3 and -2 or a net charge of +1.
Metals also have low electronegativities and low ionization energies.
Hence b is the correct answer.
