Hey,
The atomic number of Cr is 24. It's electronic configuration can be written as:
1s2 2s22p6 3s23p6 4s1 3d5 (According to Aufbau's principle 4s will be filled first and then 3d will be filled)
The 19th electron of Cr will reside in 4s orbital. The quantum numbers can be given as:
n=4
l=0 (s)
m=0
s=+1/2
