atom - Answer✅✅the smallest unit of an element that still holds the properties of
the element. Made up of protons, neutrons, and electrons
proton - Answer✅✅positively charged, located in the nucleus of the atom, has a
mass of 1AMU
neutron - Answer✅✅neutral charge, located in the nucleus of the atom, has a mass
of 1 AMU
electron - Answer✅✅has a negative charge, orbits outside of the nucleus, has a
mass of 1/1836 AMU
balanced atom - Answer✅✅same number of protons and electrons
ion - Answer✅✅atom with an unbalanced charge--either positive or negative.
isotope - Answer✅✅an atom with a different number of neutrons than the
standard amount for that element.
, atomic mass - Answer✅✅the amount of matter that makes up an atom. Estimate in
AMUs by adding up the protons and neutrons.
atomic number - Answer✅✅The number of protons an atom has. This defines the
type of element.
half-life - Answer✅✅the time it takes for half of the atoms of a particular substance
to disintegrate.
carbon dating - Answer✅✅Method of measuring the ratio of Carbon 14 to Carbon
12. The longer something has been dead, the "more" carbon 12 it has. Only accurate
on items <50,000 years old.
periodic table of elements - Answer✅✅Elements are arranged in rows according to
their atomic number, and columns loosely according to their chemical properties.
compound - Answer✅✅a substance of 2 or more elements (ex. H20--water, CO2--
carbon dioxide, NaCL--table salt)
ionic bond - Answer✅✅bonds a metal with a non-metal. One atom loses an
electron to form a positive ion, and the other gains an electron to form a negative
ion; creating an electrostatic force that holds them together.
covalent bond - Answer✅✅a bond formed when atoms share 1 or more of their
valence electrons.
chemical change - Answer✅✅the chemical composition of a substance is altered.
hint: fire is an example of a chemical change taking place.
catalyst - Answer✅✅something that starts a chemical change (ex. a spark)
mixture - Answer✅✅material that can be separated by physical means into two or
more substances
solution - Answer✅✅homogenus mixture in which one substance is completely
dissolved into another substance (ex. salt water)
suspension - Answer✅✅a mixture in which small particles are kept dispersed by
agitation or molecular motion in a surrounding medium (ex. muddy river water)
physical change - Answer✅✅a change from one state to another without a change
in the chemical composition of a substance
compression - Answer✅✅changes the volume of a substance
states of matter - Answer✅✅solid, liquid, gas, plasma
