- 4. refers to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure.
- 8. a covalent bond in which the bonded atoms have an unequal attraction for the shared electrons.
- 9. are orbitals of equal energy produced by the combination of two or more orbitals on the same atom.
- 11. a covalent bond in which one pair of electrons is shared between two atoms.
- 12. is the simplest collection of atoms from which an ionic compound's formula can be written.
- 14. 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.
- 20. a chemical bonding that results from the electrical attraction between cations and anions.
- 23. indicates the relative numbers of atoms of each kind in a chemical compound by using atomic symbols and numerical subscripts.
- 25. bonds that have an uneven distribution of charge.
- 27. is composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal.
- 28. indicates the kind, number, arrangement, and bonds but not the unshared pairs of the atoms in a molecule.
- 29. are simply double, triple, or multiple covalent bonds.
- 30. is the energy released when one mole of an ionic crystalline compound is formed from gaseous ions.
Down
- 1. the chemical bonding that results from the attraction between metal atoms and the surrounding seas of electrons.
- 2. the intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule.
- 3. states that repulsion between the sets of valance-level electrons surrounding an atom causes these sets to be oriented as far apart as possible.
- 5. is created by equal but opposite charges that are separated by a short distance.
- 6. the energy required to break a chemical bond and from neutral isolated atoms.
- 7. a chemical bonding that results from the sharing of electron pairs between two atoms.
- 10. a charged group of covalently bonded atoms.
- 13. a neutral group of atoms that are held together by covalent bonds.
- 15. the intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneous dipoles.
- 16. shows the types and numbers of atoms combined in a single molecule of a molecular compound.
- 17. formulas in which atomic symbols represent nuclei and inner - shell electrons, dot - pairs of dashes between two atomic symbols represent electron pairs in covalent bonds, and dots adjacent to only one atomic symbol represent unshared electrons.
- 18. is the mixing of two or more atomic orbitals of similar energies on the same atom to produce new hybrid atomic orbitals of equal energies.
- 19. a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge.
- 21. a chemical compound whose simplest units are molecules.
- 22. a mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together.
- 24. is the ability of a substance to be drawn, pulled, or extruded through a small opening to produce a wire.
- 26. is the ability of a substance to be hammered or beaten into thin sheets.
