(a) Interpretation: The element in the given pair with larger atomic radius needs to be determined. Concept introduction: Atomic radius is defined as the distance of the outermost electron from the nucleus of the atom. The size of the atom increases on moving from top to bottom in a group. This is due to addition of a new shell around the nucleus. Similarly, on moving from left to right in a period, atomic number increases due to which nuclear charge increases and results in decrease in the atomic size.

Interpretation Introduction
(a)
Interpretation:
The element in the given pair with larger atomic radius needs to be determined.
Concept introduction:
Atomic radius is defined as the distance of the outermost electron from the nucleus of the atom. The size of the atom increases on moving from top to bottom in a group. This is due to addition of a new shell around the nucleus. Similarly, on moving from left to right in a period, atomic number increases due to which nuclear charge increases and results in decrease in the atomic size.
Interpretation Introduction
(b)
Interpretation:
The element in the given pair which has the larger atomic radius needs to be determined.

Indicate the physical state for each of the following elements at 25 °C and normal pressure. Classify each element as a metal, nonmetal, or semimetal: (a) barium (b) boron (c)bismuth (d) bromine
Give TWO reasons why aluminium metal was not commonly used till last century, even
though it is one of the most common elements on earth.
(b)
Why are copper and lithium such important elements today?
Element X is a metal with a valency 2. Element Y is a non-metal with a valency 3
(a) Write equations to show how X and Y form ions.
(b) If Y is a diatomic gas, write the equation for the direct combination of X and Y to form a
compound.
