ATOMIC STRUCTURE MCQ Quiz: GKFix - Bridge of Knowledge

Question 1

In a multi-electron atom, what determines the energy of an electron?

Only principal quantum number
Only azimuthal quantum number
Both principal and azimuthal quantum numbers
Spin quantum number

Question 2

In hydrogen atoms, what is the term for orbitals with the same energy?

Isotopes
Isobars
Degenerate
Hybrid

Question 3

What is the correct order of energy levels in hydrogen atoms?

1s = 2s < 2p = 3s
1s < 2s < 2p < 3s
1s < 2s = 2p < 3s = 3p = 3d
1s < 2p < 2s < 3d

Question 4

What is the primary reason for the staggering of orbital energies in multi-electron atoms?

Nuclear charge only
Electron spin
Electron repulsion and shielding
Atomic size

Question 5

How does the energy of orbitals change in multi-electron atoms compared to hydrogen?

Orbitals with same n have same energies
Orbitals with same l have same energies
Orbitals with same n have different energies
Orbitals with same m have same energies
