Revising the Atomic Model

Rutherford atomic model explained why metals when heated more and more they give different colors.

• True

• False

Bohr proposed that an electron is found only in specific circular paths, or orbits, around the nucleus.

• True

• False

Each electron in an orbit has.....................energy level/s.

• two

• no

• a fixed

Electrons need to gain energy to move from a higher energy level into a lower one.

• True

• False

A ....................... of energy is the amount of energy required to move an electron from one energy level to another.

• quantum

• Wavelength

• Amplitude

The energy levels in an atom are equally spaced.

• True

• False

................... came from the mathematical solutions to the Schrödinger equation.

• The quantum mechanical model

• Classical mechanics

The energy levels of electrons in the quantum mechanical model are labeled by the principal quantum numbers (.........).

• n

• l

• s

.................... is the area around the nucleus where the probability of finding the electron is greater

• Electron cloud

• Nucleus

Each principal quantum number contains within it an energy sublevel
