Ionic or Covalent?

How do I find out whether a bond is covalent or ionic, and whether it's polar or non-polar?
For example, NaCl or CH4?

Re: Electrostatic Coulomb Potential Energy

LAW: This law states that the force between two charged objects is directly proportional with their charge and inverse-squared proportional with the distance between two charged particles. You have this equation -> F= kq1q2/r2 The larger the charge on the two ions, the greater the force between them...

Use the same model for helium but suppose that the box is 100. pm long, because the atom is smaller. Estimate the wavelength of the same transition.

I know the answer to this problem but lack understanding of what the question really is asking and how to do this.

Re: G11

First, you have the molarity (.278) . That's a given. Check mark. You have the mmol, which you convert to mol to come out to .0045 mol. Check Mark, that's given to you. Now all you have to do is find the volume. You have the formula Molarity = Mol divided by Liters (Volume). Boom boom, you plug in t...
