Question
Sodium metal crystallizes in a body centred cubic lattice with unit cell edge length of 4 Å. The radius of sodium atom is ________× 10–1 Å (Nearest integer)
Answer: .
💡 Solution & Explanation
The relation between edge length and radius in bcc lattice is 4R = a given a = 4A° 4R = x R = 1.732A° = 17.32 × 10–1 = 17
