Answer 2

Given:

The elements ¹⁶⁵Ho and ¹⁴⁰Ce.

To Find:

The difference of size between the given atoms.

Calculation:

- The atomic size of Holmium (¹⁶⁵Ho) atom = 176 pm

- The atomic size of Cerium (¹⁴⁰Ce) atom = 181.8 pm

- The difference between size of ¹⁶⁵Ho and ¹⁴⁰Ce atoms = 181.8 - 176

⇒ The difference between size of ¹⁶⁵Ho and ¹⁴⁰Ce atoms = 5.8 pm

- Hence, ¹⁶⁵Ho is greater in size than ¹⁴⁰Ce atom by 5.8 pm or the size difference between ¹⁶⁵Ho and ¹⁴⁰Ce is 5.8 pm.
