I'm trying to determine a good way to determine what compounds are ionic or covalent. I have for example, C3H8. This is 3 carbons and 8 Hydrogens. Their valence shells have 1 and 4. This is not even close to being an octet. Any help...?

First off, you are not counting the electrons in propance correctly( C3H8). Each carbon doeas have four bonds, two electrons for each bond, and thus the octect rule is followed. Hydrogen only has one electron to share, so it only has one bond and two valence electrons and is an exception to the octet rule. Basically anything that contains two non metals will be covalently bonded. Bonding between a metal and non metal will be ionic.

apparently, this turned right into a question on a Chemistry attempt of mine today. yet that aside, the superb element to do may be to attempt for conductivity of electrical energy even as molten. remember that ionic compounds have a tendency to habit electrical energy even as dissolved in water, even as covalent compounds do not.

Most every time you will be correct if--Carbon or Hydrogen is present, it will probably be 'Covalent', or if both elements are negative.
Smaller compounds like CO2 and H2O are exceptions to above.
Also if one element is + and the other - it is ionic.
Get an "A".
