Resource summary
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
