the smallest part of an element that still has the properties of that element
Atom
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction
Molecule
anything that has mass and occupies space composed of atoms
Matter
does not have affinity of water, Water fearing, Does not dissolve in water EX. Oil
Hydrophobic
Has affinity for water, water loving, usually dissolves easily in water, Ex. Salt and sugar
Hydrophilic
Unequal distribution of charges, one side is more positive and one side is more negative, dissolves in water, Ex.Water
Polar
no separation of charge so no positive or negative poles are formed, does not dissolve in water, Ex. Co2, O2, lipids, oil
non-polar
attraction between molecules of the same substance, water sticking to water
cohesion
the type of attraction that happens between two different molecules, glass, soil, plant tissue; sticks to other things
adhesion
temperature of water does not change easily, water has to absorb more heat energy to increase overall temperature compared to other compounds
high specific heat
does the dissolving(Water)
solvent
natural
organic
small, basic sub-units, think about a brick or a word
monomers
larger more complex structures made of monomers, think about a brick wall or sentence
polymers
that control the rate of biochemical reactions
enzyme
