THIS is a very large and important work, and one which cannot fail to be useful to the scientific chemist. It is divided into several parts, and contains, or rather consists of, tables of the elements ...

The properties of elements and compounds can be explained by considering the different types of bonding present inside the molecules. All ionic compounds have a high melting point and boiling point.

There are some exceptions though. For example, mercury is a liquid at room temperature. The metals in Group 1, such as lithium, sodium and potassium, are all soft. Many non-metals have low melting and ...
