Respuesta :

It is option A 4s cause n=4, l=1 this is 4s orbital

The electron will be located in is 4p in a hydrogen atom..

Given:

Three quantum numbers for an electron in a hydrogen atom in a certain state:

n = 4, l=1, [tex]m_l=1[/tex]

To find:

The location of an electron.

Solution:

  • The principal quantum number is given by n. It tells the energy level or orbit in which the electron is residing.
  • Angular momentum quantum number is given by l. It is the shape of an orbital in an orbit in which an electron is found. Each value of 'l' corresponds to the definite shape of an orbital.
  • The magnetic quantum number is given by [tex]m_l[/tex]. It tells us the orientation of the orbital in which electron is present

The principal quantum number, n = 4

The angular momentum quantum number = l = 1 = p-orbital

The magnetic quantum number = [tex]m_l[/tex] = -l  to +l = -l , 0, +1

The electron will be located in is 4p in a hydrogen atom.
