CH.5-6 Vocab

General Chemistry ch.5-6

Octet Rule Atoms tend to have 8 electrons
Valence Electrons Found in the outer most shell, which determines the atom;s chemical properties
Polyatomic Ion A change group of two or more bonded atoms considered a single Ion
Salt Ionic Compound forms when a metal atom or positive radical replaces the hydrogen of an acid
VSEPR Theory A theory that predicts that valence electrons surrounding an atom repel each other
Molecular Orbital The space where shared electrons move
Lewis Structure Uses dots to represent valence electrons
Dipole A molecule where one particle has a positive charge and the other has a negative charge
Ion Atom or molecule that has gained or lost electrons
Unshared Pairs Non bonding pairs of electrons' lone pairs
Ionic Bond Form between ions of opposite charge
Bond Length The distance between 2 bonded atoms at their minimum potential
Electronegative A measure of the ability of an atom in a chemical compounds to gain electrons
Cation Loss of electrons-ion is positive charge
Non-polar Covalent Bond Electrons in the molecule orbital are shared equal
Crystal Lattice Structure of ions-ionic compounds, not molecule compounds
Polar covalent bond A shared pair of electrons s held more closely by on of the atoms
Triple Bond A covalent bond in which 2 atoms share 3 pairs of electrons
Anion Gain of electrons-ion in negatively charged
Resonance Structure 2 or more possible configuration of possible configuration of the same compound that have identical shape but different arrangement of electrons
