Question

niobium crystallises in body centred cubic structure.If density is 8.55g cm^-3 calculate atomic radius of niobium using its atomic mass 93*10^-6

Answer 1

Answer:

14.29 nm

Explanation:

Atomic radius)^3 =Zeff × A.wt/( P×Na)

a^3= 2×94/ 8.55 ×6.02×(10)^23

a^3= 3.27× 10^(-23) cm^3

a=14.29 × 10^(-7) cm
