Question

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

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

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

Answer 1

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

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

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, nitrogen, sulphur, and carbon) are non-metals.
