Solution:

Since we have ml=-1

it shows that it has two 2e- i;e it fond in 2nd subshell in f orbital. And each subshell can hold 2 e-.

Thus the required answer is 2 electrons hold by an atom.

The number of electrons in an atom with the given set of quantum numbers is 2 electrons found in f-orbital.

The given parameters;

  • energy level of the electron, n = 7
  • angular momentum, l = 3
  • magnetic moment, ml = -1

The given quantum numbers corresponds to the followings;

n = 7, l = 3 and ml = -1, correspond to  f-orbital ([tex]7f^{14}[/tex])

The number of electrons in the orbital is written as;

number of electrons corresponding to "-1" in f-orbital =  2 electrons      

There are 2 electrons in the f-orbital with corresponding to the given quantum number and we can conclude that the number of electrons in an atom with the given set of quantum numbers is 2.
