Solids: definite shape and volume
States of Matter Liquids: definite volume
Gases: no definite shape or volume
Physical: color, size, shape
Properties of Matter
Chemical: flammability, reactivity
Physical: change of state
Changes in Matter
Chemical: composition changes
1) Matter is made up of small particles called atoms.
2) All atoms of the same element are identical.
3) Atoms of 2 or more elements combine to make
John Dalton Theory
compounds.
4) Chemical reaction involves chemical
rearrangement.
1. Protons p+
Subatomic Particles 2. Neutrons no
3. Electrons e-
Atomic Number # of protons = # of electrons
Mass Number # of protons + # of neutrons
Atoms of the same element that have different
Isotopes number of neutrons; therefore mass number is
different.
The "average atom" of each element's weighted
Atomic Mass average mass of all naturally occurring isotopes of
that element.
Electron Shells 2s, 6p, 10d, 14f
Decreases down a group; increases from L to R
Ionization Energy
across a period.
Alpha Particle 4/2 He; lowest energy
0/-1; fast moving electrons; little mass but great
Beta Particle
energy
Gamma Rays Highest Energy
Positron 0/+1; Positive electron
