How can I tell that a Carbon atom and Hydrogen atom will bond to become non-polar? I know they do, but I have no clue how I could know that.
Is there some pattern I can follow to tell what atoms form polar when bonded and which form non-polar? I understand the basic Bohr model, simple covalent bonding, and octet rule. I do not understand how I can tell which atom will form what type of bond with another certain atom when their valence electrons don’t add up to 8.
I’m pretty much taking a high school level course again. I hope I don’t bore you.
That’s basically the idea. The greater the difference in electronegativity between atoms involved in bonding, the more likely it is that the bond between them will be polar to ionic. In the case of CH4, it is easier for the carbon atom to share electrons with the hydgrogens than it is to assume a formal charge of -4, which it would have to do if it were to form complete ionic bonds with the hydrogens. It’s not always easy to predict when bonds will be ionic or covalent, and there is a continuum of polarity between completely ionic and completely covalent depending on the atoms involved and the specifics of their electron configurations.
