5th Block Fall 24 Chapter 4 Test

Visible light, X rays, infrared radiation, and radio waves all have the same

• energy.
• wavelength.
• speed.
• frequency.

The product of the frequency and the wavelength of a wave equals the

• number of waves passing a point in a second.
• speed of the wave.
• distance between wave crests.
• time for one full wave to pass.

If electrons in an atom have the lowest possible energies, the atom is in the

• ground state.
• inert state.
• excited state.
• radiation-emitting state.

The angular momentum quantum number indicates the

• orientation of an orbital around the nucleus.
• direction of the spin of the electron in its orbital.
• shape of the orbital.
• main energy level of an orbital.

A spherical electron cloud surrounding an atomic nucleus would best represent

• an s orbital.
• a p orbital.
• a combination of two p orbitals.
• a combination of s and p orbitals.
