2. Atom
The word atom comes from the Greek word meaning “incapable of being divided.”
The definition of atom is: the smallest part of an element; indivisible by ordinary chemical means.

3. Parts of the Atom Protons: Have a positive charge. +
Neutrons: Uncharged or neutral. +-
Electrons: Have a negative charge. –
Protons and electrons are equal in strength, and must be balanced.
Atoms with same charge repel, with opposite charge attract.

4. Planetary Model of an Atom
The planetary model of an atom portrays the atom as a miniature solar system in which the protons and neutrons are clustered at the center of the atom in the atomic nucleus.

5. Orbital Model of an Atom
This modern model of atomic structure, called the orbital model, has proved to be more useful in predicting the chemical behavior of atoms.
