An electron cloud

• represents a 50% probability of finding an electron

• has uniform density

• can be called an orbital

• can only show where the electron is not located

  SHOW ANSWER

Particles whose motions are better described by quantum mechanics can only gain or lose energy in discrete units called

• Protons

• Quanta

• Electrons

The de Broglie wave equation showed that the wavelength of any moving object is equal to

• h/mv

• v/mh

• hm/v

Determined that electron paths cannot be predicted and exist inside the Electron Cloud.
