Page 11: The (a) energy and the most stable electron arrangement for each element is called the (b) state.
Page 11: CHOOSE ALL of the CORRECT configurations. This means that the atom's electrons are in the ground state. (HINT: look closely at the exponents!)

Page 11: Energy is added in the form of heat and (a) the atom. The heat excites and gives energy to the (b) in the atom.
Page 12: Match the term to the correct definition:
the atom emits a specific amount of energy as the electron returns to a
ground state
the electron is in the lowest possible energy level
excited state
the amount of energy associated with the emitted light is related to the
lower energy level
the electron has gained energy and is in a higher energy level
frequency & wavelength of the light wave
the pattern formed when light emitted by an element is separated into the different wavelengths of light it contains
atomic emission spectrum
Page 11: Label the diagram
Page 11: Electrons do not stay in the (a) state for very long. When the excited electron returns to the (b) state, the atom (c) of absorbed energy in the form of (d) .
Page 11: When does an atom release light energy?
when the atom absorbs energy
when the electron gets excited & jumps to a higher energy level
when the electron returns to the ground state
when the nucleus gains a proton
Page 11: At which position is energy released in the form of light?
Page 11: Match the element name to the correct configuration:
