5 Themes in Book - CORRECT ANSWER - -organiziation
-information
-matter&energy
-evolution
Species - CORRECT ANSWER - type of organism
Systematics - CORRECT ANSWER - subfield in biology; study of evolutionary
relationships
Metabolism - CORRECT ANSWER - overall set of chemical reactions (or energy
conversions) that take place in a cell or organism
Hypothesis - CORRECT ANSWER - is tested; can accept or reject
Theory - CORRECT ANSWER - idea that is broadly explanatory and studied many times
over many years
Atoms - CORRECT ANSWER - basic building block of matter
,Elements - CORRECT ANSWER - cannot be broken down by chemical reactions
Bohr Model - CORRECT ANSWER - inner, middle, and outer most shell diagram
Protons - CORRECT ANSWER - (+), in nucleus, 1 AMU
Electrons - CORRECT ANSWER - (-), in orbitals or shells, mass is negligible
Neutrons - CORRECT ANSWER - non-charged, in nucleus, 1 AMU
Atomic Number - CORRECT ANSWER - number of protons in nucleus
Mass Number - CORRECT ANSWER - # of protons PLUS # of neutrons
Isotopes - CORRECT ANSWER - different forms of an element that differ by the Mass
Number
Ion - CORRECT ANSWER - a charged particle that forms when atom GAINS or LOSES
an electron
Cation - CORRECT ANSWER - POSITIVELY charged ion
Anion - CORRECT ANSWER - NEGATIVELY charged ion
Ionic Bond - CORRECT ANSWER - when cations and anions attract each other
, Ionic Compounds - CORRECT ANSWER - compounds formed by IONIC BONDS;
"salts"
Covalent Bond - CORRECT ANSWER - SHARING of a pair of valence electrons by two
atoms
Molecule - CORRECT ANSWER - two or more atoms held together by COVALENT
BONDS
Single Covalent Bonds - CORRECT ANSWER - ONE pair of electrons are shared
Molecular Formula - CORRECT ANSWER - tells us the number of the element (H20,
CH4, NH3)
Double Covalent Bond - CORRECT ANSWER - TWO pairs of electrons are shared
Triple Covalent Bond - CORRECT ANSWER - THREE pairs of electrons are shared
Electronegativity - CORRECT ANSWER - the attraction of a particular atom for electrons
of a COVALENT bond (this differs for each element)
Non-Polar Covalent Bond - CORRECT ANSWER - when electrons are shared EQUALLY
and result in a non-polar molecule (ex: hydrogen gas)
Polar Covalent Bond - CORRECT ANSWER - when electrons are UNEQUALLY shared
and result in a polar molecule (ex: Ammonia)
Hydrogen Bond - CORRECT ANSWER - a weak bond that forms between OPPOSITELY
charged regions of POLAR molecules (only polar bonds can have these)
