(b) Smallest atomic radius in Group 2A (c) Largest atomic radius in the second period. (d) Smallest atomic radius in the second period. (e) Largest ionization energy in Group 7A. (f) Lowest ionization energy in Group 7A

Expert Solution
Interpretation Introduction

(a)

Interpretation:

The element with the largest atomic radius in group 2A is to be determined.

Concept Introduction:

In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.

### Explanation of Solution

As we move from left to right in a row of a periodic table the atomic radius of elements decreases, while going down the group the atomic radius of the elements increases...

Expert Solution
Interpretation Introduction

Interpretation:

The element with the smallest atomic radius in group 2A is to be stated.

Concept Introduction:

In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.

Expert Solution
Interpretation Introduction

(c)

Interpretation:

The element with the largest atomic radius in 2nd period is to be stated.

Concept Introduction:

In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.

Expert Solution
Interpretation Introduction

(d)

Interpretation:

The element with the largest atomic radius in second period is to be stated.

Concept Introduction:

In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.

Expert Solution
Interpretation Introduction

(e)

Interpretation:

The element in group 7A with the largest ionization energy is to be determined.

Concept Introduction:

In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.

Ionization energy is measure of how difficult it is to remove the most loosely held electron from an atom in the gaseous state, higher the difficulty in removing the atom; higher will be the ionization energy.
