Science Quiz - Naming Compounds Flashcards
1
Q
Ionic Compounds
A
- Metal + non-metal
- Metal comes first, then non metal
- Ends in “ide.”
- Regular crisscross (equal 0)
- Example - NaCl - Sodium (capital letter) chloride.
2
Q
Multivalent Compounds:
A
- Still Metal + Non-Metal but METAL HAS MULTIPLE CHARGES
- Metal comes first, then non metal
- Ends in “ide.”
- Regular crisscross (equal 0), but figure out what kind of charge
- Things may have been reduced, check first.
- Use Roman numerals
- Example - PbO2 = Lead (IV) oxide
3
Q
Polyatomic Ions:
A
- Still Metal + Non-Metal but (usually) METAL HAS MULTIPLE ATOMS THAT ACT AS ONE (!IN BRACKETS!)
- Metal comes first, then non metal
- Ends in “ate.”
- Regular crisscross (equal 0), but everything within the brackets stays, overall charge (outside bracket) gets crisscrossed.
- Example - Ca(Oh)2 = Calcium hydroxide
4
Q
Diatomic Elements:
A
- The SAME non-metals bonded to EACHOTHER.
- HOBrFINCl
- Written as Gas with 2
- Example - H2 = Hydrogen has
5
Q
Molecular Compounds:
A
- Now Non-metal + non metal
- Second element ends in “ide.”
- Add greek prefixes to show the number of each element.
- DO NOT ADD “mono” TO FIRST ELEMENT, JUST SECOND.
- Example - CS2 = Carbon disulfide
