Answer 1

For the last three electrons which are in 5p orbital

Principal quantum number, n= 5

For the principal quantum number 5 we can have four values of Azimuthal quantum number, from 0 to n-1

= 0,1,2,3,4(s,p,d,f,g)

Since the three electrons are in the p subshell,

Azimuthal quantum number,l = 1

Magnetic quantum number of the last three electrons has values ranging from -l to +l = -1,0,+1

Spin quantum number =±½ for all the electrons
