How many unpaired electrons are present in ground state of chromium -Z-24-

Question

Toppr Admin · Accepted Answer

Correct option is C- -6-Six-The electronic configuration for Cr -24- is - 1s-2-160-160-2s-2-160-160-2p-6-160-3s-2-160-160-3p-6-160-160-4s-1-160-160-3d-5-The no- of-160-unpaired electrons is 6-160-due to half-filled subshells -4s and 3d- which are more stable than incompletely filled-160-subshells-

How many unpaired electrons are present in ground state of chromium $$(Z=24)$$?

Correct option is C. $$6$$
Six.
The electronic configuration for Cr (24) is : 1s$$^2$$ 2s$$^2$$ 2p$$^6$$ 3s$$^2$$ 3p$$^6$$ 4s$$^1$$ 3d$$^5$$.

The no. of unpaired electrons is 6 due to half-filled subshells (4s and 3d) which are more stable than incompletely filled subshells.
