Electron Configuration and Quantum Numbers

These flashcards cover key concepts about electron configuration, quantum numbers, and principles governing atomic structure.

What are the maximum number of electrons that can occupy the s sublevel?

2 electrons.

What is the shape of the p sublevel orbital?

Dumbbell shape.

According to the Aufbau Principle, how do electrons fill orbitals?

Electrons occupy the positions of the lowest energy level first.

What is Hund's Rule?

Electrons in the same sublevel occupy empty orbitals before they pair up.

What does the Pauli Exclusion Principle state?

Two electrons in the same orbital must have opposite spins.

What does isoelectronic mean?

Atoms of two different elements with the same number of electrons.

What are quantum numbers?

Quantum numbers are used to describe the position and energy of electrons in an atom.

What are the four quantum numbers?

Principal quantum number (n), Angular momentum quantum number (l), Magnetic quantum number (m), and Electron spin (ms).

What is the maximum number of orbitals in the f sublevel?
