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
