basic chemistry
- is made up of
- chemical elements
- containing
- matter
- is
- anything that takes up
space and has mass
- has
- many diverse forms
- such as
- solid, liquid, and gas
- composed of
- living
- both are made up of
- elements
- substance that
cannot be broken
down to simpler
susbstance with
different
properties
- have
- 6 main elements
- consist of
- carbon
- hydrogen
- nitrogen
- oxygen
- phosphorus
- sulfur
- create
- molecules
- when
- 2 or more elements
bond together
- creating
- compounds
- made up of
- bonds
- like
- covalent
- can be
broken into
- polar
- sharing
electrons
is not
equal
- nonpolar
- sharing
electrons is
equal
- 2 atoms share
electrons
- hydrogen
- help maintain
proper function
of structure
- attraction to a slightly
positive hydrogen to a
slightly negative atom
- consist of
- atoms
- smallest part
of an element
- can be named by
- atomic symbol
- also have
- atomic number
- number of
protons in
nuclues
- then is assigned
- atomic
mass(AMU)
- mass is constant
while weight changes
- sum of protons
and neutrons
- are made of
- protons
- neutrons
- located in
- nuclues
- electrons
- found in
- electron shell
- which forms
- ions
- are formed when
- electrons move to
other atoms
- creating
- ionic bonds
- are held by
- strong attraction
between negatively
and positively charge
ions
- example
- salt
- solid substance
that separates and
exists as individual
ions in water
- can form
- isotopes
- use a
- tracer
- to
- detect molecular
changes
- by sensing
- radiation
- atoms of the
same number of
protons that
differ in the
number of
nuetrons
- nonliving
