Unit 4 practice test CC

Front

Subatomic particles that have a negative charge

Back

Electrons are subatomic particles with a negative charge, fundamental to the structure of atoms.

Front

What is Planck's Constant?

Back

Planck's Constant is a fundamental constant in quantum mechanics, valued at 6.626x10^-34 Js.

Front

Identify the incorrect electron configuration: 6f^2, 2p^5, 3d^7, 4s^3

Back

4s^3 is incorrect; the maximum number of electrons in the s subshell is 2.

Front

Which formula is used to calculate the energy of light given its wavelength?

Back

Front

If n = 3, what is the maximum number of electrons that can fit in this shell?

Back

The maximum number of electrons in the n=3 shell is 18.

Front

What is the formula for calculating the energy of a photon?

Back

Front

Define the term 'electron configuration'.

Back

Electron configuration describes the distribution of electrons in an atom's orbitals.

Front

What is the maximum number of electrons in the p subshell?

Back

The maximum number of electrons in the p subshell is 6.

Front

Explain the significance of the quantum number 'n'.

Back

The quantum number 'n' indicates the principal energy level of an electron in an atom.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases, and vice versa.
