What is an Atom?
• Atoms are the smallest particle units of MATTER—EVERYTHING is made of atoms
• Made of three ‘subatomic’ particles:–PROTON (+)–NEUTRON (no charge)–ELECTRON (-)

What is an Atom?
• The NUCLEUS, or the core of the atom, contains PROTONS and NEUTRONS
• Electrons orbit the nucleus at different energy levels. This is called the ELECTRON CLOUD

What is an Element?
Oxygen (O), Carbon (C), Hydrogen (H),
and Nitrogen (N) make up 96% of the human body:
10,000,000,000+ cells

What is an Ion?
• An atom that has lost or gained electrons to take on a positive or negative charge
Na+A Sodium ion
Cl-A Chloride ion

How do Atoms Combine?
Atoms link together by forming chemical BONDS
Two main types of bonds:
1. Ionic Bonds Based on the electrical force between oppositely-charged ions
2. Covalent Bonds Electrons are shared between atoms

What is a Molecule?
Two or more atoms are joined by COVALENT bonds to form a MOLECULE

How are Elements Organized?
Atomic Number tells the number of PROTONS and ELECTRONS in the atom
Atomic Mass tells the number of PROTONS plus the amount of NEUTRONS since these are the only two particles with a significant mass.
