making them suitable for electric cables. The greater the number of outer electrons that the metal has, the higher its melting/boiling point. This is due to the increased positive charge on the ...

When a liquid metal cools and turns into a solid, its atoms come together to form crystals. The structure of these crystals is not perfect. Sometimes an extra layer of atoms squeezes between other ...

In the diagrams presented in the other three sections, the points show where atoms would lie if there were no motion due to heat; that is, if the metal's temperature were at absolute zero (-273°C).

The metal ions form nodes that bind the arms of the linkers together to form a repeating, cage-like structure. Due to this hollow structure, MOFs have an extraordinarily large internal surface area.

The three states of matter can be represented by the particle model. This model explains the properties of substances in their different states, as well as changes of state. Interactive activity ...
