Bohr-Rutherford Model of the AtomAtomic Number - answer the number of protons (and in effect electrons) in one atom of
a specific element (labelled as Z)
Mass Number - answerthe combined number of an atom's protons and neutrons
(labelled as A)
Atomic Mass - answera weighted average (using their natural occurrence) of the mass
numbers of an element's isotopes.
Standard Atomic Notation - answer Superscript before the chemical symbol is the mass
number, subscript before the chemical symbol is the atomic number. The chemical
symbol is placed after, as stated.
Ions - answerparticles that have a positive or negative charge due to a loss or gain of
electrons. Cations are positive ions formed by losing electrons and anions are negative
ions formed by gaining electrons: a ion is represented by its charge superscripted after
its chemical symbol (Fe2+)
Energy Levels - answera possible level of energy an electron can have in an atom,
corresponding to a specific shell and orbit a certain distance from the nucleus
Bohr-Rutherford Model of Atomic Structure - answerdraw a circle for the nucleus and
write the number of protons followed with P+ and the number of neutrons followed with
N0 inside. Draw circles around the nucleus, one for each energy level. See the diagram
for the order the electrons are drawn.
