What is the orbital angular momentum quantum number,l,of the electron that is most easily remobed when ground stare aluminium is ionized
Answers
ANSWER
Now the formula for orbital angular momentum is, -> squarerootof[l∗(l+1)] * h/2π . For a p subshell azimuthal quantum number l=1. Now you can calculate. It will be 2*h/2π.

Answer:
There could be three different configuration.
Explanation:
Aluminium can release three electrons (don't be confused; electrons are released one by one) at most, so we call it trivalent.
Whenever Aluminium releases a electron, It needs a minimum energy supply, which is called ionisation potential.
When it releases its first electron from its valence shell, the ionistation potential or ionisation enthalpy needed is called first ionisation potential.
Like this, we can define second and third ionisation potentials.
So, every time it releases elctrons, it absorbs more energy and becomes excited.
So, Electronic Configuration after becoming a univalent ion (
