Question #122164

What is the maximum number of electrons that can be accommodated in each of the following?

i) n = 3

iii) a 4d subshell

iv) a 2p orbital

iv) n = 3, l = 0, ml = 0, and ms = - ½

i) n = 3

iii) a 4d subshell

iv) a 2p orbital

iv) n = 3, l = 0, ml = 0, and ms = - ½

Expert's answer

i) maximum electrons is given by 2n^{2}

so maximum electrons in n=3 is 2.3.3=18

ii) for a d subshell l=2,

no. of orbitals=2l+1=2*2+1=5

no. of electrons that can be accommodated="2\\times5=10"

iii) for a p orbital, l=1

no. of orbitals =2l+1 = 2*1+1=3

no. of electrons that can be accommodated="2\\times3=6"

iv) answer = 1
