Naming compounds will allow us to “talk” to each other about chemicals all year. There are a few rules, and you need to learn them, practice them, and use them enough until you get familiar with them.
Like baseball, it’s not enough to “know” the rules, you have to practice them so they become second nature, automatic, and normal in your own life.
Ionic Compounds form when metals form into cations and non metals accept the electrons from metals, and they form into anions. These oppositely charged ions are wildly attracted together (with ionic bonds) the strongest bonds in chemistry.
There are some rules to naming them: The 1st name rule: say the name of the metal atom. The 2nd name rule: say the name of the anion, with an “-IDE” ending to the name.
It the metal is a transitional metal (middle of the table) they don’t always follow the simple lose enough electrons to match a noble gas (become isoelectric to a noble gas). They can form any cation that is indicated by the POSITIVE numbers in the top right corner of the periodic table boxes.
Titanium can make three different ions, the +2, the +3 and the +4 cations. How cool!
Zinc (#30) only makes a +2 ion.
Naming transitional metal ions requires you to indicate WHICH CATION you are using. The formulas make it obvious, but the words will require you to say ROMAN NUMERAL II, or III, or IV for the +4 cation.
Counting in Roman Numerals from 1 to 7 are as follows: I, II, III, IV, V, VI, VII. No ions of +8 or higher exist in high school chem.
Naming Nonmetal to nonmetal compounds follow different rules (coming soon).
