Question

Q. the value of spin quantum number of an electron in hydrogen atom is

​

Answer 1

Answer:

The spin quantum number had only two possible value of the +1/2 or -1/2. If a beam of hydrogen atoms in its ground state (n = 1, ℓ = 0, mℓ = 0) or 1s is sent in the way through a region with a spatially varying magnetic field, then the beam splited into two beams.

Answer 2

Answer:

The value of spin quantum number of an electron in hydrogen atom is two.

Explanation:

There are only two possible values for the spin quantum number:

+$1$/$2$ or -$1$/$2$. A beam of hydrogen atoms in their ground state (n = $1$, ℓ =$0$, mℓ= $0$) or $1$s splits into two beams when it passes through a region with a spatially varying magnetic field.

Concept used:

The spin quantum number describes the angular momentum and direction of an electron's spin in an orbital.

• Each orbital will be able to contain two electrons. Each electron will have a spin of +$1$/$2$ and -$1$/$2$.

• Before they pair up, the electrons tend to fill the orbitals.

• As a result, the spin of the first electron in the orbital will be +$1$/$2$. When each orbital is half-filled with one electron, the electrons begin to pair up.

• The -$1$/$2$ spin of the second electron filling the orbital.

• The spin quantum number is used to determine whether an electron's spin is up or down.

• A spin up is indicated by +$1$/$2$, while a spin down is indicated by -$1$/$2$.

As a result, there are only two possible values for an electron spin quantum number.
