However, he is remembered for his search for a pattern in inorganic chemistry. Just four years before Mendeleev announced his periodic table, Newlands noticed that there were similarities between ...

The periodic table, also known as the periodic table of (the) chemical elements, is a tabular display of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is ...

MANY arrangements have been suggested, which include the radio-active elements in the periodic table. So far as I am aware, these have all attempted to confine each space in the table to a single ...

The table shows the melting points of five alkali metals. Use this information to describe how melting point changes in group 1.
