Across
- 3. the mutual sharing of one or more pairs of electrons between two atoms.
- 7. a type of chemical bond that is formed when electrons are shared equally between two atoms.
- 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
- 9. A covalent bond of bond order = 3, consisting of six electrons; one pair in a sigma bond and the other pairs in pi bonds.
- 11. the energy required to break the bonds in 1 mol of a chemical compound
- 13. a covalent bond in which two atoms share one pair of electrons
- 14. A covalent bond in which the electron density is unevenly shared between the two bonded atoms, due to a difference in electronegativity or due to inductive effects.
- 16. a structural formula in which electrons are represented by dots; dot pairs or dashes between two atomic symbols represent pairs in covalent bonds
- 18. A covalent bond of bond order = 2, consisting of four electrons; one pair in a sigma bond and the other pair in a pi bond.
Down
- 1. a compound composed of ions bound together by electrostatic attraction
- 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
- 4. the attractive force that holds atoms or ions together
- 5. a chemical compound whose simplest units are molecules chemical formula, a combination of chemical symbols and numbers to represent a substance molecular formula, a chemical formula that shows the number and kinds of atoms in a molecule but not the arrangement of the atoms
- 6. an ion made of two or more atoms
- 10. formed between two or more atoms by the transfer of one or more electrons between atoms
- 12. 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
- 15. 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
- 17. the bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
