Why is it easier to remove an electron from a paired orbital?

Since electrons repel each other, it is slightly easier to remove the electron from the paired set in the oxygen atom than it is to remove an unpaired electron from the nitrogen atom.

Are paired electrons harder to remove?

Electrons in paired spin configurations are slightly easier to remove than unpaired electrons

What does a high Zeff mean?

Effective Nuclear Charge

What is the principal quantum number of fluorine?

Quantum Numbers of the elements

Hydrogen 2S1/2 2P1/2
oxygen 3P2 1S0
Fluorine 2P3/2 2D3/2
Neon 1S0 3F2
sodium 2S1/2 4K11 / 2

In which of the following Aufbau principle is violated?

In (D), the s-orbital (low energy) is not fully filled and electrons enter in the p-orbital (higher energy), thus violating the aufbau principle.

What is the principal quantum number and its symbol?

Rules

Name Symbol Range of values
Principal quantum number n 1 n
Azimuthal quantum number (angular momentum) ? 0 n − 1
Magnetic quantum number (projection of angular momentum) mℓ −ℓ mℓ
Spin quantum number ms −s ms s

When the principal quantum number of an electron increases what must happen?

When the principal quantum number of an electron increases, what must happen? When an electron’s principal quantum number n increases, the energy of the electron must necessarily increase. What subshell is described by the quantum numbers n=1 and l=0?

What type of orbital does an electron with n 3 and L 2 occupy?

principal quantum number (n) → energy level in orbitals and its value could be any positive integer starting from 1 to infinity. The quantum numbers provided are n = 3 and l = 2. This corresponds to the 3d subshell. A d subshell has 5 orbitals, and each orbital can hold a maximum of 2 electrons.
