Front

What is the electron configuration for an oxygen atom?

Back

1s² 2s² 2p⁴

Front

What is the noble gas configuration for phosphorus?

Back

[Ne] 3s² 3p³

Front

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

Back

2

Front

What is the relationship between wavelength and frequency?

Back

λ = c/f, where λ is wavelength, c is the speed of light, and f is frequency.

Front

Calculate the wavelength of light with a frequency of 5.2 x 10²¹ Hz. (c = 3.0 x 10⁸ m/s)

Back

5.8 x 10⁻⁵ m

Front

What is an orbital diagram?

Back

A visual representation of the arrangement of electrons in an atom's orbitals.

Front

How many electrons can the second energy level hold?

Back

8

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 Hund's Rule?

Back

Electrons will fill degenerate orbitals singly before pairing up.

Front

What is the significance of noble gas configurations?

Back

They represent a stable electron arrangement, often associated with low reactivity.
