Ions and Bonding CA Study Cards
| Question | Answer |
|---|---|
| What are valence electrons? | electrons in the outermost shell |
| What is the octet rule? | atoms gain, lose, or share electrons to get the stable number 8 valence electrons |
| According to the octet rule, how many valence electrons makes an atom or ion stable? | 8 |
| How many valence electrons make an atom or ion stable when they are in the first shell? | 2 |
| Individual vertical columns on the periodic table are called what? | Groups |
| How many valence electrons do all elements in Group 2 have? | 2 |
| How many valence electrons do all elements in Group 17 have? | 7 |
| How many valence electrons do all elements in Group 13 have? | 3 |
| How many valence electrons do all elements in Group 1 have? | 1 |
| How many valence electrons do all elements in Group 15 have? | 5 |
| How many valence electrons do all elements in Group 14 have? | 4 |
| How many valence electrons do all elements in Group 16 have? | 6 |
| How many valence electrons do all elements in Group 18 have? | 8 (except He) |
| What is the charge of a cation? | positive |
| What is the charge of an anion? | negative |
| In order to become a cation, an atom must do what? | LOSE electrons |
| In order to become an anion, an atom must do what? | gain electrons |
| All Group 1 elements become cations with what charge (oxidation #)? | 1+ (+1) |
| Group 15 elements have what oxidation # as anions? | 3- (-3) |
| Group 13 elements have what charge as ions? | +3 (3+) |
| Group 17 elements have what oxidation # (charge as an ion)? | 1- (-1) |
| Group 18 has what oxidation number? | 0 or none |
| Group 2 elements have what charge as ions? | 2+ (+2) |
| Group 16 elements have what oxidation number? | 2- (-2) |
| Why do Groups 15, 16, and 17 form anions instead of cations? | their valence # is above 4, so It takes less energy for them to gain electrons to become stable |
| Why do Groups 1, 2, and 13 form cations instead of anions? | their valence # is less than 4, so it takes less energy to lose 1, or 2, or 3 electrons for them |
| By forming ions, what are atoms trying to achieve? | a stable # of valence electrons or valence shell |
| Gaining electrons forms which kind of ions? | anions (negative ions) |
| Losing electrons forms which kind of ions? | cations (positive ions) |
| Metals tend to do this to become stable when forming ions. | lose electrons |
| Nonmetals tend to do this to become stable when forming ions. | gain electrons |
| The Transition Metals also tend to give up 1 or more electrons to become stable. True or False? | True |
| Group 17 is called what family? | Halogens |
| Group 2 is called what family? | Alkaline Earth Metals |
| Which group is the Noble Gases? | Group 18 |
