Question | Answer |
---|---|
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 |
