When an atom gains electrons, its radius increases. Elements with small atomic radius havea greater attraction for electrons, and therefore have a higher electronegativity. A molecular compound that does not ionize in water, preventing the solution from conducting electricity. How many moles of LiOH are needed to exactly neutralize 2. Formula Dot diagram for: Sneed just swallowed CH4 methanenatural gas is a molecule made of one carbon atom with four hydrogen atoms bonded to it.
To determine for sure if a bond is ionic, look up the electronegativities of the two bonding elements on ReferenceTable S and take their difference.
