Naming Compounds Flashcards
Monatomic Cations do?
They keep the elements name.
EX- K+ Potassium Ion
What if a element can make multiple Cations?
Roman numerals are placed after the elements name
EX-Fe2+ Iron(ll) Ion.
What do monatomic anions have?
The ending of the element is replaced with -ide
EX- H- Hydride
What is a Ionic Compound?
A compound bonded together by electrical forces.
What is a Polyatomic ion?
A ionic compound of more than 1 element.
Polyatomic cations that form from Nonmetals have…..
Names that end in -ium.
EX Hydronium.
Polyatomic anions can be named…..
Named -ide like monatomic ions or -ate for the most common oxyanion and -ite for a oxyanion with 1 less oxygen atom but the same charge.
Something with a oxyanion and hydrogen has?
Hydrogen or dihydrogen as a prefix.
All acidic compounds contain?
Hydrogen.
What is a binary acid?
A acid with hydrogen and another element. They don’t contain oxygen.
They have the prefix hydro-, the name of the monatomic anion of the other element, then change the -ide to -ic, lastly add acid to the end.
EX- HCl- Hydrochloric acid.
What is a acidic compound with oxygen?
A oxyacid.
How do you name an oxyacid with a anion ending in -ate.
Start with the name of the anion. Change the -ate to a -ic. Add the word acid to the end.
EX- Nitric Acid.
How to name oxyacids a with an anion ending in -ite.
Start withe the name of the anion. Then change the -ite to a -ous. Then add a acid to the end.
EX- Nitrous Acid.
What is Chemical Nomenclature?
The system for naming compounds.
To name a molecular compound from its formula, one must?
Write the element that is most electropositive (or if they are in the same family, write the element with the highest atomic #) first. Then write the name or the second element. Change the ending of the second element to -ide. Then use a Greek prefix to represent the number of atoms per element.
