Chemistry I Chapter 5

Front

When wavelength goes up, frequency goes _________.

Back

down

Front

Which rule states that electrons in the same sub-level will spread out to take their own orbital and will only double-up when they are forced?

Back

Hund's rule

Front

How many electrons can be held by a single orbital?

Back

2

Front

Which rule states that two electrons that occupy the same orbital must spin opposite directions?

Back

Pauli exclusion principle

Front

How many energy sublevels are in the second principal energy level?

Front

What is the relationship between wavelength and frequency?

Back

They are inversely related; as one increases, the other decreases.

Front

Define 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.

Front

What is the Aufbau principle?

Back

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

Front

How many principal energy levels are there in an atom?

Back

There are seven principal energy levels.
