Match the following terms with their definitions. Write ONLY the NUMBER that is in the column on the left of the definitions in the answer field next to each term. (There are more definitions than needed.) Terms: nonpolar covalent bond – [9] ideal gas- [8] lattice energy – [10] hybridization- [1] Definitions: 1 model that describes the changes in the atomic orbitals of an atom when it forms a covalent compound 2 covalent bond formed by overlap of atomic orbitals along the internuclear axis 3 volume of 1 mole of gas at STP, approximately 22.4 L for gases behaving ideally 4 covalent bond in which electrons are not shared equally 5 force exerted per unit area 6 covalent bond formed by side-by-side overlap of atomic orbitals 7 tendency of an atom to attract electrons in a bond to itself 8 hypothetical gas whose physical properties are perfectly described by the gas laws 9 covalent bond in which electrons are shared equally or almost equally 10 energy required to separate one mole of an ionic solid into its component gaseous ions

Answer True (T) or False (F): The SiF4 molecule is polar. [a] The bromine atom in the bromodifluoride anion, BrF2-, is sp3d – hybridized. [b] Consider the following partial Lewis Dot Structure: Br-F . (each element has 3 lone-pair electrons not shown). The singe bond shared between them is a polar bond and the more negative atom is Br. [c]
