Question

Polonium adopts a cubic structure with an edge length of the cube being $0.336nm$. The distance between the polonium atoms which lie at the corners along the body diagonal is:

• A. $0.336nm$
• B. $0.291nm$
• C. $0.582nm$
• D. $0.481nm$

Answer 1

The correct option is C $0.582nm$

The distance between polonium atoms which lie at the cornrers along the body diagonal is $a\sqrt{3}$

$d=a\sqrt{3}=0.336\sqrt{3}=0.582$ $nm$
