Down: 1) a compound composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal.2) a formula in which atomic symbols represent nuclei and innershell electrons, dot-pairs or dashes between two atomic symbols represent electron pairs in covalent bonds, and dots adjacent to only one atomic symbol represent unshared electron.4) the energy released when one mole of an ionic crystalline compound is formed from gaseous ions5) a formula that indicates the kind, number, arrangement, and bonds but not the unshared electron pairs of the atoms in a molecule.6) A double or triple bond7) a covalent bond produced by the sharing of one pair of electrons between two atoms. Across: 3) the bonding in molecules or ions that cannot be correctly represented by a single Lewis structure.8) an electron-configuration notation in which only the valence electrons of an atom of a particular element are shown, indicated by dots placed around the element's symbol.9) the energy required to break a chemical bond and form neutral isolated atoms.10) the simplest collection of atoms from which an ionic compound's formula can be established.
