Electronegativity is how:
large are neutral atoms
easy it is to remove an outside electron
hungry atoms are for more outside electrons
the number of protons in the nucleus
Atomic radius is:
the size of a neutral atom

the number of protons
What class of elements are better conductors?

When electrons orbit the nucleus of an atom in an unheated or unexcited state they are said to be in their:
state which releases colored light
Light of a certain color wavelength is released from an atom when?
just as it is heated in a flame
when its outside electrons are first excited when heated in a flame
after an already excited set of outside electrons then releases energy as the electrons then cool off and return to their ground state
when an atom's outside electrons are in their ground state
