Electron Models and Quantum Numbers

Front

What is an s orbital?

Back

An s orbital is a type of atomic orbital that is spherical in shape and can hold a maximum of 2 electrons.

Front

What are the four quantum numbers?

Back

The four quantum numbers are: principal quantum number, angular momentum quantum number, magnetic quantum number, and spin quantum number.

Front

What does the principal quantum number indicate?

Back

The principal quantum number indicates the main energy level or shell of an electron in an atom.

Front

What is the shape of a p orbital?

Back

A p orbital has a dumbbell shape and can hold a maximum of 6 electrons.

Front

How many orbitals are in the d sublevel?

Back

The d sublevel contains 5 orbitals.

Front

What is the maximum number of electrons that can occupy the f sublevel?

Back

The f sublevel can hold a maximum of 14 electrons.

Front

Who proposed the Bohr model of the atom?

Back

Niels Bohr proposed the Bohr model of the atom, which describes electrons in specific, allowed orbits around the nucleus.

Front

What is the significance of the angular momentum quantum number?

Back

The angular momentum quantum number determines the shape of the orbital.

Front

What does the magnetic quantum number specify?

Back

The magnetic quantum number specifies the orientation of the orbital in space.

Front

What is the spin quantum number?

Back

The spin quantum number describes the intrinsic spin of an electron, which can be either +1/2 or -1/2.
