Matter and Atom

Is anything that has mass and occupies volume. It is composed of Atoms

Matter

Four main states of Matter

Solid,Liquid,Gas,Plasma

Three characteristics of matter

Mass,Volume,Density

_______ has mass, which is a measure of its resistance to changes in motion

Mass

Matter occupies space and has a definite_______

Volume

Matter has____,which is defined as mass per unit volume

Density

6 examples of Matter

Atom and Molecules,Elements and Compounds,Solid,Liquid,Gas,Plasma

Is a scientific explanation of the structure and behavior of Atoms

Atomic Theory

Are the smallest units of chemical elements

Atoms

Atoms are made up of three subtomic particles

Protons,Neutrons,Electrons

Where do protons and electrons live?

Nucleus

The center of the atom

Nucleus

Electrons orbit around the nucleus in energy levels

Electron Shells

The number of protons in an atom’s nucleus determines the element identitiy

Atomic number

List the three Main atomic theories

Dalton’s Atomic Theory{1803},Rutherford’s Nuclear Model{1911},Bohr's Atomic Model{1913}

What theory suggest that atoms are invicible, and compounds are formed when atom share and exchange electrons

Dalton’s Atomic Theory

What theory suggest that Atoms have a small,dense nucleus surrounded by atoms

Rutherford’s Nuclear Model

What theory suggest that electron occupy specific enery levels around the nucleus

Bohr’s Atomic Model

List the three important concepts

Ionization,Chemical bonding,Radioactivity

What concept suggest that atom gain or lose to form ions

Ionization

What concept suggest that atom share or exchange electrons

Chemical Bonding

What concept suggest that atoms emit energy or particles form the nucleus

Radioactivity
