Front

What is an orbital in the context of atomic structure?

Back

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

Front

How many types of orbitals are there in the second energy level?

Back

There are two types of orbitals: s and p.

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 Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.
