Atomic Structure

Atomic structure is all about the periodic table.  It is about atoms, and how everything is made up of atoms.  Atomic Structure is very easy to get it has an atomic number and a mass number for every atom.        The atomic number of an atom is the number of protons it has, and the atomic mass is the number of protons plus the number of neutrons.  All atoms remain with out a charge, because they have an equal amount of protons and neutrons.

This is an element as you would see it in the periodic table.  At the top the 27 is the atomic number, meaning there i 27 protons and 27 electrons.  Then the Co is the symbol and it stands for Cobalt. The last number is the 58 and that means that cobalt has 31 neutrons.

This is a chart to show the positions of all the particles in an atom.  As you see the neutrons and protons are located in the nucleus.  Then the electrons are on the outer ring of the atom.

Chemistry- is the study of properties, and the behavior of matter.

This is the branch of science that deals with all the changes matter and properties undergo.

Matter-  All the actual stuff in the universe.

The only thing that isn't matter, is energy.

The basic forms of matter are liquid, gas and solids.

Molecule- is a substance that has two or more atoms with a definite agreement held together by chemical bonds.

Diatomic Molecule- Contains only two atoms.

Polyatomic Molecule- contains more than two atoms.

Mixture- A mixture consists of two or more different substances chemically combined.

the are two types of mixtures

heterogeneous- means different you can see all the different types of substances.

homogeneous- means the same, you can see all the parts of the mixture.

Solution- is a special type of mixture

It is a homogeneous mixture that contains a solute and a solvent.

solute- the solid part that gets dissolved

solvent- the liquid part that dose the dissolving

Matter- is all the substances that have mass and volume.
Chemical Change- is any change that results in a formation of a new chemical substance, chemical change happens on the molecular level.  It involves in the making or breaking of bonds. examples: iron rusting, mild souring, gasoline burning, or bread rising.
Physical Change- Physical change requires energy to be transferred. It requires rearrangement of molecules but doesn't affect their internal structure.  examples: boiling water, dissolving salt into water, or cutting up a potato.  

Here is a youtube video on the difference between chemical and physical change. It helps to further show the differences between the two.
