Properties of Matter: Solids
In a solid, these particles ... form crystals that are composed of oppositely charged ions: a positively charged cation and a negatively charged anion. Because of the strong attraction between opposite charges, it takes a lot of energy to overcome ionic bonds.
What If the Forces that Form Molecules Were Stronger (Or Weaker)?
the forces that form molecules were stronger or weaker? Complex molecules are created thanks to bonds that form between ... that the two particles, if freely existing, would combine. One would get nothing more than neutral neutrons, which have a mass ...
Scientists Use Self-Assembly to Make Molecule-Sized Particles With Patches of Charge
Scale bars: 2 µm (PhysOrg.com) -- Physicists, chemists and engineers at the University of Pennsylvania have demonstrated ... electrical charges of calcium ions — just like the calcium in teeth and bone — can form bridges between negatively charged ...

Adventures in Ethics and Science
As promised at the end of my post on polar and non-polar molecules, here’s a basic concepts post on intermolecular forces. Intermolecular forces are the forces between ... charge spread over a very big ion. In any compound where the atoms form ionic ...
