Chemistry - Bonding

4. a chemical bond in which three pairs of electrons are shared between two atoms.
6. a combination of chemical symbols and numbers to represent a substance
8. a formula that indicates the location of the atoms, groups, or ions relative to one another in a molecule and that indicates the number and location of chemical bonds
10. a structural formula in which electrons are represented by dots; dot pairs or dashes between two atomic symbols represent pairs in covalent bonds
11. a group of atoms that are held together by chemical forces; the smallest unit fo matter that can exist by itself and retain al of a substance's chemical properties
13. the energy required to break the bonds in 1 mol of a chemical compound
14. a compound composed of ions bound together by electrostatic attraction
17. a chemical compound whose simplest units are molecules
18. a bond formed when atoms share one or more pairs of electrons
19. the attractive force that holds atoms or ions together
20. a force that attracts electrons from one atom to another, which transforms a neutral atom into an ion

1. a covalent bond in which a pair of electrons shared by two atoms is held more closely by one atom
2. the collection of atoms corresponding to an ionic compound’s formula such that the molar mass of the compound is the same as the mass of 1 mol of formula units
3. a chemical formula that shows the number and kinds of atoms in a molecule, but not the arrangement of the atoms
5. an ion made of two or more atoms
7. 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
9. the bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
12. a covalent bond in which the bonding electrons are equally attracted to both bonded atoms
15. a covalent bond in which two atoms share one pair of electrons
16. a chemical bond in which two pairs of electrons are shared between two atoms.
