Down: 1) a molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive2) a bond formed when two atoms share a pair of electrons3) a molecular orbital that can be occupied by two electrons of a covalent bond6) a chemical formula of a molecular compound that shows the kinds and numbers of atoms present in a molecule of a compound7) a molecule that has two poles, or regions, with opposite charges9) one of the two or more equally valid electron dot structures of a molecule or polyatomic ion10) the energy required to break the bond between two covalently bonded atoms; this value is usually expressed in kJ per model of substance11) a chemical formula that shows the arrangement of atoms in a molecule or a polyatomic ion; each dash between a pair of atoms indicates a pair of shared electrons16) a covalent bond between atoms in which the electrons are shared unequally19) a tightly bound group of atoms that behaves as a unit and has a positive or negative charge Across: 4) attractions between molecules caused by the electron motion on one molecule affecting the electron motion on the other through electrical forces; these are the weakest interactions between molecules5) a neutral group of atoms joined together by covalent bonds8) attractive forces in which a hydrogen covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom11) a bond formed when two atomic orbitals combine for form a molecular orbital that is symmetrical around the axis connecting the two atomic nuclei12) a covalent bond in which three pairs of electrons are shared by two atoms13) a bond angle of 109.5 degrees that results when a central atom forms four bonds directed toward the center of a regular tetrahedron14) a bond formed by the sharing of electrons between atoms15) a pair of valence electrons that is not shared17) intermolecular forces resulting from the attraction of oppositely charged regions of polar molecules18) a compound that is composed of molecules20) an orbital that applies to the entire molecule21) a covalent bond in which the bonding electrons are most likely to be found in sausage-shaped regions above and below the bond axis of the bonded atoms22) also known as "Polar Covalent Bond"23) a covalent bond in which one atom contributes both bonding electrons24) a molecule consisting of two atoms25) a bond in which two atoms share two pairs of electrons26) a solid in which all of the atoms are covalently bonded to each other27) the two weakest intermolecular attractions-dispersion interactions and dipole forces28) a covalent bond in which the electrons are shared equally by the two atoms29) valence-shell electron-pair repulsion theory; because electron pairs repel, molecules adjust their shapes so that valence electron pairs are as far apart as possible30) the mixing of several atomic orbitals to form the same total number of equivalent hybrid orbitals
