,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)
