In an elenent tgere is 4elements on its outer shell is it a metal or non metal

Dear Student

Nonmetals, generally, have 4 or more valence (outer shell) electrons while metals tend to have 4 or less.
There are two exceptions to this rule: Hydrogen and helium.
Hydrogen is a non-metal having 1 electron in the valence shell and helium is a non-metal having 2 electrons in the valence shell.

It is a non-metal.

It can be metal or non metal both but more chance of non metal

they can be both metal as well as non metal.
for example. carbon and silicon are non metal with 4 electrons in outermost shell.
whereas titanium and zirconium are metals with 4 electrons in outermost shell.
