What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, which determines its chemical properties.

Front

What is the significance of valence electrons?

Back

Valence electrons are the outermost electrons of an atom and are involved in chemical bonding.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons corresponds to the group number in the periodic table for main group elements.

Front

What is the difference between s, p, d, and f orbitals?

Back

s orbitals are spherical, p orbitals are dumbbell-shaped, d orbitals have more complex shapes, and f orbitals are even more complex.

Front

What is the maximum number of electrons that can occupy an s orbital?

Back

2 electrons.

Front

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

Back

6 electrons.

Front

What is the Aufbau principle?

Back

Electrons fill orbitals starting from the lowest energy level to the highest.

Front

What is Hund's rule?

Back

Electrons will occupy degenerate orbitals singly before pairing up.

Front

What is the Pauli exclusion principle?

Back

No two electrons in an atom can have the same set of four quantum numbers.
