Respuesta :
C. the maximum number of electrons.
Explanation:
Principle quantum number
In electronic configuration of an atom the Orbits or Shells are denoted using n.
K=1, L=2, M=3, N=4 ................ and so on. This number n is of significance which denotes the energy level where the electrons are found.
Orbital Angular Momentum Quantum Number (l)
The orbital angular momentum no. [tex]l[/tex] denotes the subshell of the electron. It tells the shape of the subshells as well.
s subshell corresponds to l=0, p subshell corresponds to l=1, d subshell corresponds to l=2, f subshell corresponds to l=3, and so on.
Magnetic Quantum Number (m)
Magnetic quantum no. denotes the no. of orbitals present in the subshell.
Each orbital can hold a maximum of 2 electrons both having opposite spin.
The no. of orbitals is taken from the angular momentum quantum number having given as [tex](2l+1)[/tex]
Now the magnetic quantum no. ranges from [tex]-l\ to\ +l[/tex] which includes zero in the middle.
There are n² number of orbitals found in an energy level.
Spin Magnetic Quantum Number (S)
Spin quantum no. can have values either [tex]-\frac{1}{2}\ or\ +\frac{1}{2}[/tex]
orbitals cannot contain two electrons of the same spin.
Electron with positive sign is known as alpha electron and the negative one is called beta electron.
