The metallic radius of an aluminum atom is 143 pm. What is the volume of an aluminum atom in cubic meters?

6.61 * 10∧-29 m³

Explanation:

Given dа ta:

Atomic radius = 143 pm = 143 * 10∧-12 m

volume = ?

Formula:

r = a/2√2

143 * 10∧-12 m = a / 2√2

a = 143 * 10∧-12 m * 2√2

a = 404.4 * 10∧-12 m

where a is edge length, so we can calculate the volume by using following formula:

volume = a³

V = (404.4 * 10∧-12 m) ³

v = 6.61 * 10∧-29 m³
