Across
5.A bond in which a pair of electrons is distributed or shared equally between two atoms.
6.donor-acceptor type of covalent bond.
13.The hybrid formed by the superposition of the different resonance structures.
16.recognized the the existence of some forces acting on particles close with each other.
19.A compound which is held together by ionic bonds; composed of one or more cations (+ charged ions) and one or more anions (- charged ions).
22.having an uneven distribution of charge
24.measure of unequal sharing of electrons indicated by difference in electro negativity values.
25.the force of attraction between molecules
26.the bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
27.A covalent bond in which the electrons are shared unequally, resulting in a partially negative end and a partially positive end.
28.The product of the charges at one center and the distance between the positive and the negative centers.
29.a covalent bond produced by the sharing of two pairs of electrons between two atoms.
Down
1.A type of intermolecular force that occur in nonpolar molecules.
2.the energy required to break a chemical bond and form neutral isolated atoms.
3.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
4.A type of force, occurs between dipole or polar molecules.
6.a chemical compound that is formed by the sharing of electrons.
7.transfer of electrons from one atom to another.
8.The mixing of atomic orbitals to form new orbitals, of equal energy suitable for bonding.
9.develop special symbolism, in which dots are use to show the number of valence electron of an atom.
10.Arrangement of the atoms within a given molecule.
11.electrons that are not involved in bonding and that belongs exclusively to one atom
12.Number of covalent bonds formed by the atom.
14.bond formed by sharing electrons.
15.the pair of electrons are contributed equally by the two atoms.
17.a charged group of covalently bonded atoms
18.the degree to which each atom joined to another in a chemical bond contributes to the valency of this other atom.
20.Rule that says, atoms tend to gain, loses or share electrons so as to have eight electrons in their outer electron shell.
21.the distance between the nuclei of bonded atoms.
23.chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
