Across
- 3. composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal
- 7. a covalent bond in which one pair of electrons is shared between two atoms
- 10. indicates the kind number arrangment and bonds but not the unshared pairs of the atoms in a molecule
- 12. simplest collection of atoms from which an ionic compound formula can be established
- 13. the energy required to break a chemical bond and formal neutral isolated atoms
- 14. a charged group of covalently bonded atoms
- 15. intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneouse dipoles
- 20. results from the sharing of electron pairs between to atoms
- 22. the mixing of two or more atomic orbitals of similar energies on the same atom to produce a new hybrid atomic orbitals of equal energies
- 24. shows the type and numbers of atoms combined in a single molecule of a molecular compound
- 27. the repulsion between the sets of valence level electrons surrounding an atom causes these sets to be oriented as far as possible

Down
- 1. refers to bonding in molecules or ions that cannot be correctly represented by a single lewis structure
- 2. atomic symbols represent nuclei and inner shell electrons dot pairs or dashes between two atomic symbols represent electron pair in covalent bonds and dots adjacent to only one atomic symbol represent unshared electrons
- 4. an uneven distribution of charge
- 5. a chemical compound whose simplest units are molecules
- 6. the ability of a substance to be drawn or pulled or extruded through a small opening to produce a wire
- 8. chemical bonding that results between cations and anions
- 9. created by equla but opposite charges that are seperated by a short distance
- 11. represented by placing dots around a particular element
- 15. the energy released when one mole of an ionic crystalline compound is formed from gaseious ions
- 16. a covalent in which the bonding electrons are shared equally by the bonded atoms resulting in a balanced distribution of electrical charge
- 17. a covalent bond in which the bonded atoms have an unequal attraction for the shared electrons
- 18. orbitals of equal energy produced by the combination of two or more orbitals on the same atom
- 19. a mutual electrical attraction between the nuclei and valance electrons of different atoms that bind atoms together
- 21. chemical bonding that results from the attraction between metal atoms and surrounding sea of electrons
- 23. indicates the relative numbers of atoms of each kind in a chemical compound by using atomic symbols and numerical subscripts
