Chemistry

Matter is what the Universe is made up of (stuff used to make anything). It is composed of Elements.

GAS where atoms move freely. LIQUID where atoms have less movement. SOLID atoms have very little movement.

The ability to put matter into motion or 'do work'.

(Kinetic - energy in action).(Potential - inactive or stored energy).Chemical - potential energy becomes kinetic energy (nutircian absorbed thru digestion becoming "fuel to run" the body).Electrical - movements of charged particles called "ions".Mechanical - physically moving matter (riding a bike needs us to move the pedals to move the bike).Radiant - electromagnetic spectrum (xrays, infarred/heat, light, radio or ultraviolet).

O, C, H, N.On the periodic table.

Atoms are the building blocks of Matter.They are composed of 3 main 'subatomic' particles

Is when 2 or more Atoms bond together, forming a molecule.

Covalent bonds - share electrons.Ionic bonds - electrons are transferred (given away or taken).

Polar - electrons are not shared evenly.Non Polar - electrons are shared evenly.Hydrogen bond - Bridge formed between H2O molecules, proteins and DNA.

With their outer most shell called the 'Valence shell'.

Compound that increases in Hydrogen ions when dessolved in water.Compound that increases Hydroxide ions when dessolved in water.

Measures Hydrogen ions in a solution.

Organic molecules are the molecules that are built around chains of carbon atoms. There are four main groups of organic molecules that combine to build cells and their parts: carbohydrates, proteins, lipids, and nucleic acids.
