What is an orbital diagram?

Back

An orbital diagram is a visual representation of the electron configuration of an atom, showing the distribution of electrons in atomic orbitals.

Front

What is the Balmer-Rydberg equation used for?

Back

The Balmer-Rydberg equation is used to predict the wavelengths of spectral lines in hydrogen and other hydrogen-like atoms.

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, and orientation.

Front

What does the principal quantum number (n) indicate?

Back

The principal quantum number (n) indicates the main energy level of an electron in an atom, with higher values of n corresponding to higher energy levels.

Front

What is the maximum number of electrons in an energy level?

Back

The maximum number of electrons in an energy level is given by the formula 2n², where n is the principal quantum number.

Front

What is the shape of an s orbital?

Back

An s orbital has a spherical shape and can hold a maximum of 2 electrons.

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 (3 orbitals: px, py, pz).

Front

How many orbitals are in the d subshell?

Back

The d subshell contains 5 orbitals, which can hold a maximum of 10 electrons.

Front

What happens to the energy of an electron as the principal quantum number increases?

Back

As the principal quantum number increases, the energy of the electron also increases.

Front

What is the relationship between the principal quantum number and the average distance of an electron from the nucleus?

Back

As the principal quantum number increases, the average distance of the electron from the nucleus also increases.
