What are Ions?
Daily Double: this model of the atom has discrete orbitals with distinct energy levels that accounted for atomic emission spectra of Hydrogen
What is Bohr's model.

Planck's equation
What is E=hv
Block of elements: electrical conductivity, luster, malleability, little variation in size and hard solids
What are Transition Metals
What is: atoms tend to gain or lose electrons to achieve a full set of valence electrons - usually 8 electrons in a valence shell.
