Chemistry 2nd Quarter exam review correct verified answers

Chemistry 2nd Quarter exam review Chemical bond - correct answers Mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together. Point of chemical bonding - correct answers The atoms want to become more stable Ionic bonding - correct answers The chemical bond resulting from electrical attraction between large numbers of cations and anions Cation - correct answers Positive ion Anion - correct answers Negative ion Covalent bond - correct answers Chemical bond resulting from the sharing of an electron pair between two atoms Polar-Covalent bond - correct answers Covalent bond where the bonded atoms have an unequal attraction for the shared electrons Non-Polar Covalent bond - correct answers Covalent bond where the bonding electrons are shared equally by the bonding of atoms resulting in a balanced distribution of electrons charge Diatomic elements - correct answers H-O-N-Cl-Br-I-F, Hydrogen, Oxygen, Nitrogen, Chloride, Bromide, Iodine, Florine Octet rule - correct answers Chemical compounds tend to form where they gain, lose or share electrons, and has an octet (set of 8) electrons in its highest occupied energy level Lewis structures - correct answers Dot diagram that provides visual representations of valence electrons in a covalent bond between atoms of a molecule. Shared electron pair - correct answers Electrons between atoms that have formed covalent bonds Unshared electron pair - correct answers Electron pair not involved in chemical bonding. Also frequently referred to as a "lone pair". Single bond - correct answers A covalent bond where two atoms share one pair of electrons Multiple bond - correct answers A double or triple bond in a covlaent bond Ionic compound - correct answers Compound composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal
