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. Non-metals are limited to the elements in the upper right hand corner of the Periodic Table.

hope it will help you ❣️❣️

An element is a metal if it loses electron.
Or has less than 4 electrons in its valence shell.
Or is an s/d/f block element [ Except Boron family which is p block however some of them behave as metals ].
The elements which don’t match with any of the above criteria are non metals.

If an atom loses electron then it is CATION
If an atom gains electron then it is an ANION.
