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

What is an orbital diagram?

Back

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

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.
