Chemestry and our environment
:
Atomic structure
Electrons
Neutrons
Protons
Z = atomic number
Atomic structure is the arrangement of subatomic particles within the atom
states of matter
-Solid
-Liquid
-Gas
Plasma
hot ionized gasses
eletrically charged
the most common state of matter
Kinetic Theory
All matter is composed by small particles
particles are in constant motion
particles constantly collide with eachother or with the wall of the container
Solid Liquid Gas

Solid matter is hard. It has shape and volume.
Liquids. This state of matter may fill a container. It has not a shape but has a thickness and may be of different colors.
Gases. They surround us in the air
Polymers and plastic
Polymers:
A polymer is a substance or material consisting of very large molecules, or macromolecules, composed of many repeating subunits.
Polymer Examples:
Nylon
Polyester (PET)
Polystyrene (PS)
Polylactic acid (PLA)
Polythene (PE)
Polyvinylchloride (PVC)g
Biological polymers:
starch
cellulose
DNA
Synthetic polymers:
nylon
polystrene
kevlar
PE
PET
Waterproof polymers
Acrylic polymer
Atmosphere
Our atmosphere is made of
21% oxygen
78% nitrogen
early vulcanic atmosphere:
methane (CH4)
carbond dioxide (CO2)
ammonia (NH3)
steam (H2O)
