Independent Variable - correct answer The experimental factor that is manipulated; the variable
whose effect is being studied.
dependent variable - correct answer The outcome factor; the variable that may change in
response to manipulations of the independent variable.
Theory - correct answer A hypothesis that has been tested with a significant amount of data
Essential Elements - correct answer elements an organism needs to live a healthy life and
reproduce
Trace Elements - correct answer required by an organism in only minute quantities
Iodine Deficiency - correct answer goiter
Atom - correct answer Smallest unit of matter that still retains the properties of an element
Neutrons - correct answer no charge
,protons - correct answer positive charge
Electrons - correct answer negative charge
Daltons - correct answer Neutron mass and proton mass are almost identical and are measured
in..
Atomic number - correct answer the number of protons in the nucleus of an atom
mass number - correct answer sum of the protons and neutrons in the nucleus
Atomic mass - correct answer the atom's total mass, can be approximated by the mass number
Isotopes - correct answer Atoms of the same element that have different numbers of neutrons
Radioactive isotopes - correct answer decay spontaneously, giving off particles and energy
Applications of radioactive isotopes - correct answer dating fossils, tracing atoms through
metabolic processes, diagnosing medical disorders
Energy - correct answer The ability to do work or cause change
Potential energy - correct answer stored energy that results from the position or shape of an
object
, Electron shells - correct answer An energy level representing the distance of an electron from
the nucleus of an atom.
Valence shell - correct answer The outermost energy shell of an atom, containing the valence
electrons involved in the chemical reactions of that atom.
Valence electrons - correct answer Electrons on the outermost energy level of an atom
Chemical Bonds - correct answer the attractive force that holds atoms or ions together
Covalent Bond - correct answer A chemical bond that involves sharing a pair of electrons
between atoms in a molecule
Molecule - correct answer A group of atoms bonded together
Notation used to represent atoms and bonding - correct answer structural formula
Single bond - correct answer a covalent bond in which two atoms share one pair of electrons
Double bond - correct answer A chemical bond formed when atoms share two pairs of
electrons
Valence - correct answer The bonding capacity of a given atom; usually equals the number of
unpaired electrons required to complete the atom's outermost (valence) shell.
Electronegativity - correct answer the ability of an atom to attract electrons when the atom is in
a compound
