Dendrimers are unique molecular structures terminated by a multitude of peripheral functional groups that are accessible for targeted chemistry. Carboxyl-terminated dendrimers are attractive because ...

Listen to the full series on BBC Sounds. Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature. See the study guide on the three states of matter to ...

The formula of an ionic compound can be deduced from the formulae of its ions. Remember that for the metal elements in groups 1, 2, and 3 the charge on the ion can be deduced by how many outer shell ...

Most chemists would describe titanium dioxide as an ionic compound composed of Ti 4+ and two O 2–. Not so, suggests a theoretical analysis: TiO 2 is better described with the charge states Ti 3+ and O ...
