Ch.2 Elemental Ions
Elemental Ions, Names, Symbols, Charge, Spelling.
| Question | Answer |
|---|---|
| How do you know the charge of the Cations in the 1A, 2A, and 3A Periodic Groups? | Their charge is the same as their group number. 1A=(+1), 2A=(+2), 3A=(+3) |
| How do you know the charge of the Anions in the 5A, 6A, and 7A Periodic Groups? | Charge=(Group Number)-8 5aCharge=5-8=(-3).... 6aCharge=6-8=(-2) .... 7aCharge=7-8=(-1) |
| H :What is the Spelling and most common charge? | Hydrogen (+1) |
| Li :What is the Spelling and charge(s)? | Lithium (+1) |
| Na :What is the Spelling and charge(s)? | Sodium (+1) |
| K :What is the Spelling and charge(s)? | Potassium (+1) |
| Be :What is the Spelling and charge(s)? | Beryllium (+2) |
| Mg :What is the Spelling and charge(s)? | Magnesium (+2) |
| Ca :What is the Spelling and charge(s)? | Calcium (+2) |
| Ba :What is the Spelling and charge(s)? | Barium (+2) |
| Al :What is the Spelling and charge(s)? | Aluminum (+3) |
| F :What is the Spelling and charge(s)? | Fluorine (-1) ... Watch the 'U' |
| Cl :What is the Spelling and charge(s)? | Chlorine (-1) |
| Br :What is the Spelling and charge(s)? | Bromine (-1) |
| I :What is the Spelling and charge(s)? | Iodine (-1) |
| O :What is the Spelling and charge(s)? | Oxygen (-2) |
| S :What is the Spelling and charge(s)? | Sulfur (-2) |
| N :What is the Spelling and charge(s)? | Nitrogen (-3) |
| P :What is the Spelling and charge(s)? | Phosphorus (-3) |
| Cu :What is the Spelling and charge(s)? | Copper(I), Copper(II) ... Positive |
| Fe :What is the Spelling and charge(s)? | Iron(II), Iron(III) ... Positive |
| Sn :What is the Spelling and charge(s)? | Tin(II), Tin (IV) ... Positive |
| Pb :What is the Spelling and charge(s)? | Lead(II), Lead(IV) ... Positive |
| Hg :What is the Spelling and charge(s)? | Mercury(I), Mercury(II) ... Positive |
| Co :What is the Spelling and charge(s)? | Cobalt(II), Cobalt(III) ... Positive ...(watch the 'a' when spelling) |
| Cr :What is the Spelling and charge(s)? | Chromium(II), Chromium(III) ... Positive |
| Mn :What is the Spelling and charge(s)? | Manganese(II) ... Positive |
| Ni :What is the Spelling and charge(s)? | Nickel(II) ... Positive ... (watch the 'el' when spelling) |
| Zn :What is the Spelling and charge(s)? | Zinc(II) ... Positive ... (watch the 'c' when spelling) |
| Ag :What is the Spelling and charge(s)? | Silver(I) ... Positive |
| Which Elemental Cations receive a Roman Numeral as their charge? | Transition Metals |
| When naming Elemental Ions in a compounds what name change is associated with the METAL CATIONS (elements on the left side of the table)? | There is no name change. Their compound name is the same as their elemental name. |
| When naming Elemental Ions in a compounds what name change is associated with the Nonmetal and Metaloid ANIONS (elements on the right side of the table)? | Most commonly they will have -ite or -ate endinging (indicating there is O in the formula). Some exeptions: Hydroxide (OH-1), Cyanide (CN-1) |
| When naming Elemental Ions in a compounds what name change is associated with the Transitional Metals (the center B groups of the table). | There is no name change, but ROMAN NUMERALS are added to indicate charge. Unlike Metals, Nonmetals, and Metaloid ions, Transition metals can be associated with more than one charge. Ex: Cobalt(II)=(Co)+2 and Cobalt(III)=(Co)+3 |
