One reason the periodic table of the elements is so useful is that it is a means of arranging elements according to their similar properties. This is what is meant by periodicity orperiodic table trends. There are multiple ways of grouping the elements, but they are commonly divided into met...
Periodic Table of the Elements Introduction to the Periodic Table People have known about elements like carbon and gold since ancient time. The elements couldn't be changed using any chemical method. Each element has a unique number of protons. If you examine samples of iron and silver, you ...

of hydrogen, the elements on the left-hand side of the periodic table aremetals. Actually, hydrogen acts as a metal, too, in its solid state, but the element is a gas at ordinary temperatures and pressures and does not display metallic character under these conditions. Metal properties ...
