Energy Levels, Sublevels, and Orbitals

Front

What is an orbital?

Back

An orbital is a region in an atom where there is a high probability of finding an electron.

Front

How many energy levels are there in an atom?

Back

There are seven principal energy levels in an atom, numbered from 1 to 7.

Front

What is the maximum number of electrons that can occupy the first energy level?

Back

The first energy level can hold a maximum of 2 electrons.

Front

What are the four types of sublevels in an atom?

Back

The four types of sublevels are s, p, d, and f.

Front

How many electrons can a p sublevel hold?

Back

A p sublevel can hold a maximum of 6 electrons.

Front

How many orbitals are in a d sublevel?

Back

A d sublevel contains 5 orbitals.

Front

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

Back

A d sublevel can hold a maximum of 10 electrons.

Front

What is the shape of an s orbital?

Back

An s orbital has a spherical shape.

Front

What is the shape of a p orbital?

Back

A p orbital has a dumbbell shape.

Front

What is the Aufbau principle?

Back

The Aufbau principle states that electrons fill the lowest energy orbitals first before moving to higher energy levels.
