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.

When it comes to science, chemistry is elemental. That pun is based on the fact that the main building blocks in the branch of science are chemical elements, pure substances made from a single type of ...

An international team led by scientists of GSI/FAIR in Darmstadt, Johannes Gutenberg University Mainz and the Helmholtz Institute Mainz, succeeded in determining the chemical properties of the ...

Electronegativity generally increases as you move from left to right across a period in the periodic table. It decreases as you move down a group. This means that the most electronegative elements are ...

You're listening to Chemistry in its element brought to you by Chemistry World, the magazine of the Royal Society of Chemistry. Milk, cheese, yogurt, spinach, almonds. What element do they all have in ...

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 ...
