center of an atom
outer part of an atom
What is the atomic number
number of protons
What is an Atom with a charge?
loses or gains an electron
a given element have the same number of protons in each atom, they differ in neutron number.
What is a bond between Ions, a bond between a negative and positive charge
electrons between Atoms share
radioactive dye markers
Isotope covalent Bond
electrons are shared unequally
Polar covalent bond
give water the property of life
water binds to other stuff
cohesion and adhesion
Is water a polar covalent bond?
Does water have a pacific heat?
What is the structure of water dependable on?
Hydrogen bonds forms

4 degrees celcius
contains carbon and at least on hydrogen
only carbon and hydrogen
Carbon Dioxide CO
What does the tail of fatty acid say
tell if organic and tells if hydrogen carbons
Simple sugar, monosaccharide,
Is the only one that contains 6 carbonhydrates
ready to use
how many polysaccharides are there?
complex carbohydrates with no structure
made from a plant and is very easy to break down; designed to be used.
structural of a plant that is not easily broken down
an animal polysaccharide made to be easily broken down
is an important component of the exoskeleton
does the fatty acid tail repel water
pull something out of 2 and condense into one, water is left over
used to cut polysaccharide to pieces and add water to hydrate

straight and no double bond
curve, kink on tail to digest poly saturated and unsaturated fats
no double bond
consists of a hydrophobic tail, made up of two fatty acids. the third is phosphate group small and nonpolar
Does protein start with a primary structure
long chain of amino acid
hundreds of different proteins and is the building block of cell basic component
determines the shape, shape determines the function.
