Which among the following is/are correct about chromium ?

1.	Which among the following is/are correct about chromium ?
Answer» Its electronic configuration is `3d^4 4s^1` Total spin of chromium =3 Spin multiplicity of 3d-subshell of chromium = 6 MAGNETIC moment of chromium is `sqrt(48)` SOLUTION :`Cr_(24) to 1s^2 2s^2 2p^6 3s^2 3p^6 3d^5 2s^1` Total spin = Number of unpaired electron `xx 1/2 = 6 xx 1/2 = 3` Spin multiplicity `= (2sum s+1) = 2 xx 5 xx 1/2 + 1= 6` Magnetic moment `=sqrt(N(n+2))` where n= number of unpaired electrons. `=sqrt(6xx8) = sqrt(48) ` B.M.
