2. An anion is an ion with a charge.
positive
negative
neutral
variable
3. Atoms gain or lose electrons to achieve a stable electron configuration, typically resembling that of a gas.
4. When an atom loses electrons, it forms a positively charged ion called a .
5. The charge of an ion can be predicted by its group number on the table.
6. All elements in Group 17 (halogens) tend to form ions with a -1 charge.
True
False
7. Ionic bonds are formed between two nonmetals.
True
False
8. Explain how an ionic bond is formed between a metal and a nonmetal. You may refer to the diagram below.
