Question

why atoms tend to gain or lose electrons?
plzz answer me fast dear​

Answer 1

Explanation:

Metals tend to lose electrons to attain Noble Gas electron configuration. Groups 1 and 2 (the active metals) lose 1 and 2 valence electrons, respectively, because of their low Ionization energies. ... The sodium atom gives up an electron to form the Na+ ion and the chorine molecule gains electrons to form 2 Cl- ions.
