Quantum Numbers

Front

What are quantum numbers?

Back

Quantum numbers are a set of numerical values that describe the unique quantum state of an electron in an atom, including its energy level, shape, orientation, and spin.

How many electrons can the f orbital hold?

Back

The f orbital can hold a maximum of 14 electrons.

Front

What does the principal quantum number (n) represent?

Back

The principal quantum number (n) represents the main energy level or shell of an electron in an atom, indicating its distance from the nucleus.

Front

What is the shape of an s orbital?

Back

The shape of an s orbital is spherical.

Front

What is the shape of a p orbital?

Back

The shape of a p orbital is dumbbell-shaped.

Front

What is the maximum number of electrons in a p orbital?

Back

A p orbital can hold a maximum of 6 electrons.

Front

What does the azimuthal quantum number (l) indicate?

Back

The azimuthal quantum number (l) indicates the shape of the orbital and can take values from 0 to n-1.

Front

What is the maximum number of electrons in a d orbital?

Back

A d orbital can hold a maximum of 10 electrons.

Front

Why can the 3rd energy level hold more electrons than the 2nd?

Back

The 3rd energy level can hold more electrons because it includes the s, p, and d orbitals, allowing for a total of 18 electrons.

Front

What is the relationship between energy levels and distance from the nucleus?

Back

As the principal quantum number (n) increases, the energy levels are farther from the nucleus.
