Question

The magnetic moment of cu ti and cr are in the ratio of​

Answer 1

Write the magnetic moment ratio of copper(z=29), Ti(z=22) and Cr(z=24).

Cu29 − 3d10 4s1 − has 1 unpaired electronTi22 − 3d24s2 − has 2 unpaired electronCr24 − 3d54s1 − has 6 unpaired electron Magnetic moment is calculated as n(n+2) −−−−−−−√ BM For Copper = 1(1+2) −−−−−−−√ BM = 3√ BMFor Titanium = 2(2+2) −−−−−−−√ BM = 6 −−√ BMFor Chromium = 6(6+2) −−−−−−−√ BM = 48 −−−√ BMSo the ratio is Cu : Ti : Cr = 3√ : 6 −−√ : 48 −−−√ = 1√ : 2 −−√ : 16 −−−√
