How can two electrons occupy the same space and not repel?
The two electrons exist in the same orbital while possessing the following forces :
- The electrostatic repulsion due to the negative charges they bear.
- The electrostatic attraction between the negatively charged electrons and the positively charged nucleus.
- The magnetic force of attraction due to their spinning.
Can 2 electrons have same energy?
In a single-electron atom, an electron in a 2s orbital will have exactly the same energy as an electron in a 2p orbital, because they only interact with the nucleus through a Coulombic interaction – which has spherical symmetry (it’s the same in all the directions of space; it only changes with distance to the nucleus) …
Do electrons have opposite spins attract?
Electrons with opposite spins are already in different quantum states – being in different eigenstates. So they can be in the same spatial state. This isn’t attraction, but a lack apparent repulsion. So opposite spin electrons have this attraction, though it is small compared to Coulomb’s repulsion.
How do two electrons reside in the same orbital have the same charge?
Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) two electrons in the same orbital must have opposite spins (Figure 46(i) and (ii)).
Do electrons occupy the same orbital are distinguished by?
Two electrons in the same atomic orbital can be distinguished by their spin quantum number.

Which one of the following sets of quantum numbers is possible?
(iv) n=3,l=1,ml=0,ms=+1/2. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. So , these quantum numbers are possible.
How do you know if quantum numbers are possible?
Rules Governing the Allowed Combinations of Quantum Numbers The angular quantum number (l) can be any integer between 0 and n – 1. If n = 3, for example, l can be either 0, 1, or 2. The magnetic quantum number (m) can be any integer between -l and +l. If l = 2, m can be either -2, -1, 0, +1, or +2.
