Bonding (chemistry)

2. a combination of chemical symbols and numbers to represent a substance
3. a chemical bond between two atoms involving six bonding electrons
4. a covalent bond in which a pair of electrons shared by two atoms is held more closely by one atom
5. an ion made of two or more atoms
9. the bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
13. 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
15. a covalent bond in which the bonding electrons are equally attracted to both bonded atoms
17. the attractive force that holds atoms or ions together
18. a compound composed of ions bound together by electrostatic attraction
19. a chemical formula that shows the number and kinds of atoms in a molecule, but not the arrangement of the atoms
20. the energy required to break the bonds in 1 mol of a chemical compound

1. 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. a structural formula in which electrons are represented by dots; dot pairs or dashes between two atomic symbols represent pairs in covalent bonds
7. 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
8. a chemical compound whose simplest units are molecules
10. 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
11. a covalent bond between two atoms involving four bonding electrons
12. a covalent bond in which two atoms share one pair of electrons
14. a bond formed when atoms share one or more pairs of electrons
16. a force that attracts electrons from one atom to another, which transforms a neutral atom into an ion
