Chapter Four Test

The energy of a photon, or quantum, is related to its

• mass

• speed

• frequency

• size

One of the wave properties of electromagnetic radiation, such as light, is

• volume

• frequency

• mass

• weight

Max Planck proposed that a "hot" object radiated energy in small, specific amounts called

• quanta

• waves

• hertz

• electrons

If electromagnetic radiation A has a lower frequency than electromagnetic B, then compared to B, the wavelength of A is

• longer

• shorter

• equal

• exactly half the size of B

For electromagnetic radiation, c (the speed of light) is equal to

• frequency minus wavelength

• frequency plus wavelength

• frequency divided by wavelength

• frequency times wavelength

A bright-line spectrum of an atom is caused by the energy released when electrons

• jump to a higher energy level

• jump to a lower energy level

• absorb energy and jump to a higher energy level

• absorb energy and jump to a lower energy level

When excited atoms radiate energy, the amount of energy given off is equal to

• hc

• hv

• nλ

• cv

The part of the atom where the electrons will NOT be found is in the

• area surrounding the nucleus

• nucleus

• electron cloud

• orbitals

In SI, the frequency of electromagnetic radiation is measured in

• nanometers

• quanta

• hertz

• joules

The major difference between a 1s orbital and a 2s orbital is that

• the 2s orbital can hold more electrons

• the 2s orbital has a slightly different shape

• the 2s orbital is at a higher energy level

• the 1s orbital can have only one electron
