Question

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

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

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 non-metals are solids and gases (except Bromine [Br] - liquid). Sodium, Magnesium, Iron, Gold and Calcium are metals. Oxygen, Chlorine, Helium, Sulphur and Carbon are non-metals.
