The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

His first table contained just 28 elements, organised by their valency (how many other atoms they can combine with). These elements were almost entirely main group elements, but in 1868 he ...

Gethin: And today we're going to be looking at the periodic table. Let's take a look at some Group 1 metals then - also known as alkaline metals. Fran: Group 1 elements are called the alkali metals.

Researchers have long been hunting for a way to make the elusive elements more stable so they can be better studied.

In this periodic table of elements quiz, you have 10 minutes to name as many elements as you can, given only their symbol, atomic weight and the broad group they live in. It's no mean feat ...
