Question

What is the maximum number of electrons in an atom that can have the following quantum numbers?
Express your answer as an integer.
part A. n = 3, ml = -2

part B. n = 4, l = 3

part C. n = 5, l = 3, ml = 2

Part D. n = 4, l = 1, ml = 0

Answer 1

What is the maximum number of electrons in an atom that can have the following quantum numbers?
Express your answer as an integer.
part A. n = 3, ml = -2

n =3 so l = 0,1,2 and ml = -2,-1,0,1,2

so ml=-2 represents one orbital which can have max 2 electrons
part B. n = 4, l = 3

n=4 and l=3

so it must be 4f

maximum electrons = 14

part C. n = 5, l = 3, ml = 2

n = 5 , so l = 0,1,2,3,4

l =3 so it is 5f and ml=2 so it represents only one orbital so max electrons = 2

Part D. n = 4, l = 1, ml = 0

n=4 and l =1

so 4p is the orbital

with ml =0,+1 ,-1

so it represents one p orbital

which can have 2 electrons
