1
are formed when atoms lose, gain, or share electrons.
chemical bonds
2
occurs when there is a transfer of one or more valence electrons form one atom to another
ionic bond
3
two nonmetal atoms combine,
covalent bond
4
is the equal and unequal sharing of electrons among the atoms of a molecule.
polarity
5
Bonding electrons shared equally between two atoms.No charges on atoms.
nonpolar covalent
6
Electronegativity Difference (ΔΕΝ) ≥1.7
ionic
7
Electronegativity Difference 0.5 to 1.6
polar covalent
8
Electronegativity Difference (ΔΕΝ) ≤0.4
nonpolar covalent
9
IMFA strongest to weakest
ion dipole, hydrogen bond, dipole dipole, dipole induced dipole, london forces
10
This is the amount of energy required to
stretch the surface area of liquids (e.g., 1 cm2
surface tension
11
This is a measure of a liquid’s
resistance to flow.
viscosity
12
The temperature at
which solid becomes
liquid.
melting point
13
Temperature at which the
va p o r p r e ss u r e a n d
atmospheric pressure of a
liquid substance are equal.
boiling point
14
refers to the
ability of a substance
to dissolved in a given
amount of solvent
solubility
15
refers to the minimum energy required for a reaction to take place. When a collision provides energy equal to or greater than the activation energy, product can form.
activation energy
16
refers to how hot or cold a cer tain substance is.
Usually, a rise in temperature of 10 0C doubles the reaction rate.
temperature
17
refers to the number of par tcles present in a given volume of solution
concentration
18
measure of how much exposed area a solid object has, expressed in square units.
surface area
19
the increase in the rate of a chemical reaction by lowering its activation energy.
catalysis
20
an intermediate state during a chemical reaction that has a higher energy than the reactants or the products.
transition rate
21
a probability distribution used for describing the speeds of various par tcles within a stationary container at a specific temperature.
Maxwell Boltzmann Distribution
22
simplest form of carbohydrates
monosaccharide
23
a molecule that can react with other molecule to form very large molecules or polymers
monomer
24
short chain of amino acid monomer link by peptide bonds
peptide
25
special chemical messengers that are created in the endocrine gland
hormones
26
organic compounds that combined to form proteins
amino acid
27
proteins which make the biochemical reaction fast
enzymes
28
made up of three components: nitrogen-containing base, five-carbon sugar, and a phosphate group
nucleotide
29
contain glycerol, two-fatty a and a phosphate group
phospholipids
30
are large, organic molecule such as carbohydrates, lipids, proteins, and nucleic acids.
biological macromolecules
31
primary energy source of the human body
carbohydrates
32
impor tant nutrients in your body but eating too many especially unhealthy fats such as saturated fats and trans fats can lead to heart disease, cancer, and obesity.
lipids or fats
33
composed of four elements, namely: carbon, hydrogen, oxygen, and nitrogen.
proteins
34
also known as polynucleotides
nucleic acids
35
ENERGY THAT IS GENERATED FROM NATURAL PROCESSES THAT ARE CONTINUOUSLY REPLENISHED
renewable energy
36
COMES FROM SOURCES THAT WILL RUN OUT OR WILL NOT BE REPLENISHED IN OUR LIFETIMES-OR EVEN IN MANY, MANY LIFETIMES.
non renewable energy
37
RENEWABLE ENERGY SOURCES THAT COME FROM THE REMAINS OF PLANTS AND ANIMALS THAT LIVED MILLIONS OF YEARS AGO.
fossil fuel
