- What periods mean
- number of electron shells
- Valence Electrons
- electrons in the outer-most shell
- Triple bond
- Three bonds between two atoms
- Covalent Bond
- bonds formed when atoms share electrons
- All atoms want this many valence electrons
- Eight
- Ionic Bond
- Bond formed between a positive ion and a negative ion
- Positive Ion
- Atom that has lost electrons
- Double bond
- Two bonds between two atoms
- For an atom to be nonreactive
- Needs to have a full valence shell
- Like to gain electrons
- Atoms in groups fourteen through seventeen
- Octet Rule
- Except for hydrogen and helium, the outermost energy level can hold a maximum of 8 electrons (hydrogen and helium can hold 2)
- Ions
- atom with an electric charge (positive or negative)
- Periods
- Rows on the periodic table
- Chemical Bond
