Question

A metal crystallizes in bcc lattice with edge length 4.48 Å. The radius of the metal atom is ___________ Å.

Options

• 0.68

• 1.22

• 1.94

• 2.34

Answer 1

A metal crystallizes in bcc lattice with edge length 4.48 Å. The radius of the metal atom is 1.94 Å.

Explanation:

For bcc unit cell, radius (r) of atom

= `sqrt(3)/4 "a"`

= `sqrt(3)/4 xx 4.48`

= 1.94 Å
