Across Down
11 a covalent bond between atoms in which the electrons are shared unequally
13 a covalent bond in which the electrons are shared equally by the two atoms
14 intermolecular forces resulting from the attraction of oppositely charged regions of polar molecules
15 a bond formed when two atoms share a pair of electrons
16 the two weakest intermolecular attractions - dispersion interactions and dipole forces
18 a covalent bond in which one atom contributes both bonding electrons
20 a chemical formula that shows the arrangement of atoms in a molecule or polyatomic ion
21 a covalent bond in which three pairs of electrons are shared by two atoms
22 a bond in which two atoms share two pairs of electrons
23 a compound that is composed of molecules
26 a molecule consisting of two atoms
28 one of the two or more equally valid electron dot structures of a molecule or polyatomic ion
31 valence-shell electron-pair repulsion theory; because electron pairs repel, molecules adjust their shapes so that valence electron pairs are as far apart as possible
1 an orbital that applies to the entire molecule
2 a bond angle of 109.5 degrees that results when a central atom forms four bonds directed toward the center of a regular tetrahedron
3 the mixing of several atomic orbitals to form the same total number of equivalent hybrid orbitals
4 a tightly bound group of atoms that behaves as a unit and has a positive or negative charge
5 a pair of valence electrons that is not shared between atoms
6 a molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive
7 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 atoms
8 a covalent bond between atoms in which the electrons are shared unequally
9 a neutral group of atoms joined together by covalent bonds
10 a molecule that has two poles, or regions, with opposite charges
12 the energy required to break the bond between two covalently bonded atoms
17 a chemical formula of a molecular compound that shows the kinds and numbers of atoms present in a molecule of a compound
19 attractions between molecules caused by the electron motion on one molecule affecting the electron motion on the other through electrical forces
24 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 atom
25 a solid in which all of the atoms are covalently bonded to each other
27 a molecular orbital that can be occupied by two electrons of a covalent bond
29 a bond formed by the sharing of electrons between atoms
30 a bond formed when two atomic orbitals combine and form a molecular orbital that is symmetrical around the axis connecting the two atomic nuclei
