The atomic number of chromium is `24` Its electronic coefigueration in ground state in `1s^(2) 2s^(2)2p^(6)3s^(2)4s^(1) 3d^(5)` .Chromium atom by using `3` electron from `Cr ^(2+)` .A chromium atom contain `17%` morte neutron than the proton. Now answer the following questions
The electron atom can be respresentted by the symbol
A. `._(24)Cr^(50)`
B. `._(24)Cr^(32)`
C. `._(32)Cr^(24)`
D. `._(50)Cr^(24)`
