Why do elements gain or lose electrons?

​

Octet Rule

Electrons are lost or gained to have an electron configuration like the noble gas (pseudo-isoelectric).

​

Want a valence electrons shell of 8 electrons​

Some text here about the topic of discussion

Less than 4 valence electrons (metals) lose electrons --> cation

​

More that 4 valence electrons (nonmetals) gain electrons --> anion
