Question

Observe the table and identify metals and nonmetals. Select the correct option.
$\begin{array}{ccc}\text{Sl.No}& \text{Set}-1& \text{Set}-2\\ 1.& \text{Sodium(Na)}& \text{Oxygen(O)}\\ 2.& \text{Magnesium(Mg)}& \text{Chlorine(Cl)}\\ 3.& \text{Iron(Fe)}& \text{Helium(He)}\\ 4.& \text{Gold(Au)}& \text{Sulphur(S)}\\ 5.& \text{Calcium(Ca)}& \text{Carbon(C)}\end{array}$

• A. Set - 1 (Metals) and Set - 2 (nonmetals)
• B. Set - 1 (nonmetals) and Set - 2 (Metals)
• C. Both Sets - 1 & 2 are Metals
• D. Both Sets - 1 & 2 are nonmetals

Answer 1

The correct option is A

Set - 1 (Metals) and Set - 2 (nonmetals)

Most metals are solids (except Mercury [Hg] - liquid) and have high melting points. Most of nonmetals are solids and gases (except Bromine [Br] - liquid). Sodium, Magnesium, Iron, Gold and Calcium are metals. Oxygen, Chlorine, Helium, Sulphur and Carbon are nonmetals.
