Which list represents the classification of the elements nitrogen.

The question is incomplete. Complete question is:

Which list represents the classification of the elements nitrogen, neon, magnesium, and silicon, respectively?

(1) metal, metalloid, nonmetal, noble gas

(2) nonmetal, noble gas, metal, metalloid

(3) nonmetal, metalloid, noble gas, metal

(4) noble gas, metal, metalloid, nonmetal

The correct answer is option 2) nonmetal, noble gas, metal, metalloid

Reason:

1) Non-metal are bad conductors of electricity. Also non-metal are electronegative in nature. Hence, among the provided elements, nitrogen satisfied the criteria. Hence, it is a non-metal.

2) Noble gas are the elements which have completely filled outermost shell. Hence, among the provided elements, Neon satisfied the criteria.

3) Metal are good conductors of electricity. Also metal are electropositive in nature. Hence, among the provided elements, magnesium satisfied the criteria. Hence, it is a metal.

4) Metalloid have conductivity better than non-metals but poor than conductors. Hence, among the provided elements, Silicon satisfied the criteria. Hence, it is a metalloid.
