Electron Configurations Practice Flashcard 2

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, meaning that an orbital can hold a maximum of two electrons with opposite spins.

What is the atomic symbol for Neon?

Back

Ne

Front

How many half-filled orbitals does Silicon (Si) have?

Back

Silicon has 2 half-filled orbitals.

Front

How many orbitals are in a d sublevel?

Back

A d sublevel has 5 orbitals.

Front

What is an orbital?

Back

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

Front

What is the maximum number of electrons that can occupy a single orbital?

Back

A single orbital can hold a maximum of 2 electrons.

Front

What is the shape of s orbitals?

Back

s orbitals are spherical in shape.

Front

What is the shape of p orbitals?

Back

p orbitals are dumbbell-shaped.

Front

What is the significance of electron configurations?

Back

Electron configurations describe the distribution of electrons in an atom's orbitals, which determines the atom's chemical properties.
