Nitrogen on periodic table of the elements. Do you remember how many elements there are in the periodic table? Spoiler: it’s probably different than you remember if you went to school before 2010.

Look at electron configuration of nitrogen v. phosphorous (image of box/arrow diagrams of electron configurations ... terms of lower electronegativity so positive oxidation states more likely.

The zigzag, staircase, line in the diagram of the periodic table above separates the metals, on the left, from non-metals, on the right. Hydrogen is a non-metal, but it is often put in the middle.

You interact with about two-thirds of the elements of the periodic table every day. Some, like carbon, oxygen, and nitrogen, make up our bodies and the air we breathe. Yet there is also a class of ...

If it has 7 protons, that’s nitrogen. But the logic of the periodic table also relies upon the number and organisation of electrons in an atom. Let’s take chlorine as an example. It is ...

Although metal ions are central to all of biochemistry, a group of elements clustered in the early part of the periodic table—carbon, nitrogen, oxygen and phosphorus—are highly represented in ...

You're listening to Chemistry in its element brought to you by Chemistry World, the magazine of the Royal Society of Chemistry. Keeping up with the neighbours is rarely a concern in the periodic table ...
