are ionic bonds weak?
yes
attraction between 2 opposite charged ions
ionic bonds
polar covalent bonds
one atom pulls more
-electrons don't equal
which covalent bond ---> electons don't equal
polar covalent
t/f-- nonpolar covalent bond are equal
t
non polar covalent bond
pull of both atoms
compound
substance consisting 2 or more different elements
molecule
2 or more atoms bonded together
what are valence electrons?
electrons in outter shell
how to get mass number
# of protons + neutrons
where is the mass number located on an element?
before symbol..top left
how do u find the # of neutrons?
mass#-atomic#
whats the atomic number?
number of protons in nucleus

(p=e)
where is the atomic number located at?
before element-- bottom left
what are the subatomic particles?
neutrons, protons, electrons
which subatomic particle(s)are located in the atomic nucleus?
neutons and protons
electons are around..?
cloud in nucleus
positive charge is the..?
protons
negative charge is the..?
electrons
neutrons have a charge.(t/f)
false
why is potential and kinetic energy associated in A&P?
because its how our BODY FUNCTIONS; need ENERGY FOR CELLS or bad health chem.
What are the forms of energy?
chemicla energy, electrical, mechanical energy, radiant
radiant energy
energy traveling in WAVES
mechanical energy
directly invovled in MOVING MATTER
electrical energy
movement of charged particles
chemical energy
released in chemical reaction
Potential to kinetic energy is an example of what?
chemical energy
what is the difference between mass and weight?
WEIGHT is GRAVITATIONAL FORCE acting on matter.

MASS is the amount of SPACE
what is chemistry?
its the study of atoms?
why are we studying chemistry?
becuz everything is made-up of atoms
what is the difference b/w kinetic and potential energy?
protential is stored energy. kinetic is energy in action
what does matter need to move?
energy
whats the diff. b/w matter and energy?
matter has space and mass. energy has NO space and mass/
energy
capacity to do work
3 states of matter?
solid
liquid
gas
atoms that gained or lost unequal electrons
ion
hydrogen bonds
attraction b/w polar molecules .. important in life.. they dont share or tranfer electrons
ionic bonds
weak bond is water
chemical reactions
make and break chemical bonds
whats the REACTANTS in a chemical reaction?
starting material
whats the PRODUCTS in a chemical reaction?
ending material
three types of chemical reactions
synthesis, decomposition, exchange
synthesis
requires energy input of 2 or more reactants combined
decomposition
reactants broken down into less complex
exhange
both sythesis and decomposition involved
which subatomic particle(s)are located in the atomic nucleus?
neutons and protons
electons are around..?
cloud in nucleus
positive charge is the..?
protons
negative charge is the..?
electrons
neutrons have a charge.(t/f)

why are we studying chemistry?
becuz everything is made-up of atoms
ADP-->ATP
ANABOLISM
ATP-->ADP
CATABOLISM
equallibrium
rate of product information equals rate of reactant information
what affects speeds up chemical reaction?
