, 1. Ionic bond: An ionic bond is electrostatic attraction between oppositely charged cations in anions (metals and nonmetals)
2. How does a binary ionic compound form?: A metal loses electrons (forming a cation) and donates them to a nonmetal which gains electrons informs in
anion, the compound is held together by the force of electrostatic attraction
3. Covalent bond: Attractive force between the nuclei of a molecule's atoms and pairs of electrons between
atoms; a mutual attraction of atoms for a shared pair of electrons
4. Between which types of elements do covalent bonds form?: A covalent bond usually forms between two nonmetals
5. Isoelectric: Term used to describe tow elements having the same electronic configuration; the only ditterence is the number of protons
6. Describe the trends of electronegativity: Decreases going down the table, increases from left to right
7. Pure covalent bond: A bond in which electrons are shared equally between atoms
8. Polar covalent bond: A bond in which electrons are not equally shared between atoms
9. Pure covalent electronegativity difference: less than 0.4
10. Polar covalent electronegativity difference: 0.4 - 1.8
11. Ionic electronegativity difference: greater than 1.8
12. Two nonmetals are generally . If they are directly beside each other on the table, they are
probably . If they are far away from each other, they are probably .: covalent; pure covalent; polar
covalent
13. Metals and nonmetals are generally...: ionic
14. Ionic compounds containing only monatomic ions nomenclature: 1) name of
the cation (metal)
2) name of the anion (nonmetal)........................ change ending to "-ide"
Example:
NaCl: sodium chloride KBr:
potassium bromide CsF: cesium
fluoride
15. Ionic compounds containing polyatomic ions nomenclature: 1) Name of the cation
(metal or polyatomic)
