How many electrons in an atom can share the quantum numbers n=2, l=1 and ml=1?
2 answers:
Answer : The number of electrons in an atom are, 2.
Explanation :
Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from
. When l = 2, the value of
will be -2, -1, 0, +1, +2.
Spin Quantum number : It describes the direction of electron spin. This is represented as The value of this is
for upward spin and
for downward spin.
As we are given that,
So,
(For each sub-shell)
From this we conclude that, that means there is one orbital that contains two electrons with opposite spin.
Hence, the number of electrons in an atom are, 2.

Answer: The number of moles of produced are, 3.60 moles.
Explanation :
First we have to calculate the limiting and excess reagent.
The balanced chemical equation is:
From the balanced reaction we conclude that
As, 1 mole of react with 2 mole of
So, 3.60 moles of react with
moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and
is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of
From the reaction, we conclude that
As, 1 mole of react to give 1 mole of
So, 3.60 mole of react to give 3.60 mole of
Therefore, the number of moles of produced are, 3.60 moles.
