Question

Nitrogen and Germanium are:
(A) Metal and Non-metal respectively
(B) Metal and metalloid respectively
(C) Non-metal and metalloid respectively
(D) Non-metal and metal respectively

Answer 1

There are 6 metalloids and 17 nonmetals in the periodic table. Nitrogen is found in group 15 and Germanium is found in group 14. Now these two groups along with 13th and 16th create a transition from metal to nonmetal elements and some elements in these groups are metalloids.

Complete answer:
When we move from 13th group to 16th group starting from The top of 13th group we draw a zigzag line towards the bottom of group 16th and all the elements that are there on this zigzag line are metalloids. All the elements on the left of the zigzag line are metals and all the elements on the right side of the zigzag line are non-metals.

B	C	N	O
Al	Si	P	S
Ga	Ge	As	Se
In	Sn	Sb	Te
Tl	Pb	Bi	Po

Group 13 elements: B, Al, Ga, In, Thallium(Tl)
Group 14 elements: C, Si, Ge, Sn, Pb
Group 15 elements: N, P, As, Sb, Bi
Group 16 elements: O, S, Se, Te, Po
Starting from group 13 if we draw Zigzag line then,
B will be a metalloid, after that Si, Ge, As, Sb and Te will also be metalloids.
So Germanium (Ge) is metalloid.
Nitrogen (N) is on the right side of this zigzag line so it is a non-metal.

Correct answer is Option(C)

Additional Information: Metalloids are the substances whose properties are intermediate between metals and nonmetals, that’s why metalloids are also referred to as semi metals.

Note: Nitrogen is a colorless, odorless, tasteless gas that is the most plentiful element in Earth's atmosphere and is a constituent of all living matter who has atomic number 7. Germanium is a lustrous, hard-brittle, grayish-white metalloid who has atomic number 32. Pure germanium is a semiconductor with an appearance similar to elemental silicon.
