Question

The Pauli Exclusion Principle tells us that no two electrons in an atom can have the same four quantum numbers. For an electron in the 2s orbital shown above, enter a possible value for each quantum number n= m = Give ONE example. m, = Give ONE example. et visited Though a given electron only has one value for my, there are possible mvalues for electrons in 2s orbitals.

Answer 1

for 2s orbital the possible quantum numbers as follows

n = 2

l = (n-1) => 0 , 1

ml = (-l to +l) =>

for l = 0 , ml = 0 ,

for l = 1 => -1 , 0 , +1

ms = +1/2 or -1/2

here the ml value is only one value then it is = 0 so the possible ml values are 1

answers =>

n = 2

l = 0

ml = 0 (or) -1 , 0 , +1

ms = +1/2 or -1/2

1 possible ml value
