  1. 4. a chemical bond in which three pairs of electrons are shared between two atoms.
  2. 6. a combination of chemical symbols and numbers to represent a substance
  3. 8. a formula that indi-cates the location of the atoms,groups,or ions relative to one another in a molecule and that indi-catesthe number and location of chemical bonds
  4. 10. a structural formula in which electrons are represented by dots; dot pairs or dashes between two atomic symbols represent pairs in covalent bonds
  5. 11. a group of atoms that are held together by chemical forces; a molecule is the smallest unit of matter that can exist by itself and retain all of a substance’s chemical properties
  6. 13. the energy required to break the bonds in 1 mol of a chem-ical compound
  7. 14. a compound com-posed of ions bound together by electrostatic attraction
  8. 17. a chemical com-pound whose simplest units are mol-ecules
  9. 18. a chemical bond that involves the sharing of electrons to form electron pairs between atoms.
  10. 19. the attractive force that holds atoms or ions together
  11. 20. type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

  1. 1. when atoms with different electronegativities share electrons in a covalent bond
  2. 2. the collection of atoms corresponding to an ionic com-pound’s formula such that the molar mass of the compound is the same as the mass of 1 mol of formula units
  3. 3. a chemical formula that shows the number and kinds of atoms in a molecule, but not the arrangement of the atoms
  4. 5. an ion made of two or more atoms
  5. 7. an electron-configuration notation in which only the valence electrons of an atom of the a particular element are shown, indicated by dots placed around the element’s symbol
  6. 9. the bonding in molecules or ions that cannot be correctly rep-resented by a single Lewis structure
  7. 12. a type of chemical bond that is formed when electrons are shared equally between two atoms
  8. 15. a chemical bond in which one pair of electrons is shared between two atoms.
  9. 16. a chemical bond in which two pairs of electrons are shared between two atoms.
