Question

Observe the table and identify metals and non-metals. Select the correct option.

$\begin{array}{ccc}\text{Sl.No}& \text{Set 1}& \text{Set 2}\\ 1.& \text{Sodium (Na)}& \text{Oxygen (O)}\\ 2.& \text{Magnesium (Mg)}& \text{Chlorine (Cl)}\\ 3.& \text{Iron (Fe)}& \text{Helium (He)}\\ 4.& \text{Gold (Au)}& \text{Sulphur (S)}\\ 5.& \text{Calcium (Ca)}& \text{Carbon (C)}\end{array}$

• A. Set 1: Metals and Set 2: Non-metals
• B. Set 1: Non-metals and Set 2: Metals
• C. Both Set 1 and Set 2 are metals
• D. Both Set 1 and Set 2 are non-metals

Answer 1

The correct option is A Set 1: Metals and Set 2: Non-metals

Metals are good conductors of heat and electricity. They are malleable, ductile and sonorous.

Most of the non-metals except bromine (liquid) are solids and gases.

From the table, Set 1 elements (sodium, magnesium, iron, gold, and calcium) are metals, and Set 2 elements (oxygen, chlorine, helium, sulphur, and carbon) are non-metals.
