ρ=m÷v density equation
different states of matter, differences in particle model explains
density
substances change state mass is conserved when
physical a change of state is
no new substance is produced during a change of state
reversed a substance recovers its original properties if the change is
electrons=protons atoms have no overall charge because
same number of protons atoms of the same element have
different numbers of protons atoms of different elements have
atoms of the same element with isotopes are
different numbers of neutrons
different energy level atoms are arranged in shells, each at a
0.1nm (1x10⁻¹⁰) approximate radius of an atom
positive ions: atoms lose one or more electrons
negative ions: atoms gain one or more electrons
nucleus most of an atom's mass is in the
1/10000 of an atom (1x10⁻¹⁴) radius of nucleus
higher energy level EM absorption causes electrons to move to a
lower energy level EM emission causes electrons to move to a
protons+neutrons mass number=
