For an electron in an atom to change from the ground state to an excited state,

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

The change of an atom from an excited state to the ground state always requires

The French scientist Louis de Broglie theorized that

Which model of the atom explains the orbitals of electrons as waves?

All of the following describe the Schrödinger wave equation except

A three-dimensional region around a nucleus where an electron may be found is called a(n)

According to the quantum theory of an atom, in an orbital

The velocity nor the position of an electron cannot be known at the same time according to

If the intensity of a photon is increased, but the photon has a lower energy than the electron to be ejected from a metal then
