Nicole has given up on her edict about not running any more Harry Potter pieces. It is what it is.


Over the century since its creation, the Periodic Table of Elements has been studied almost as much, if not more, comprehensively than the Harry Potter universe. It is far past time that the two academic schools of thought were combined.


In the Twentieth Century, a system of organising subjects into a simple order was invented. It quickly caught on, and has since become a worldwide shorthand for summarising complex information.

The system is, of course, the Hogwarts Houses of Gryffindor, Ravenclaw, Hufflepuff and Slytherin. They were created by J. K. Rowling in 1997, when they were originally published as ‘fiction’ in the Harry Potter series. The Houses have since been reclaimed as a social tool.

In transferring over to the real world, the sorting system has become so much more than just fictional boarding school Houses. The Houses are a personality type; a Buzzfeed quiz; a political affiliation; an allegiance stronger than blood; and for some people . . . a way of life.

Almost as famous as the most important invention of our age was the development of the Periodic Table of Elements in 1869 by the chemist Dmitri Mendeleev. The table orders atomic elements into groups based on their characteristics, behaviours and interactions. Similar, some might say, to the Hogwarts Houses.

So, how do the two systems compare? Is it possible to combine them, to create one perfect, hyper-efficient organisational tool? This publication will present a hypothesis for the possible structure of this type of system.


The procedure is simple: what happens when you mix, for example, a Gryffindor and a Slytherin? The same thing that happens when a Group 1 and Group 7 element react: explosions. Violent, but very cool, explosions.

Following careful analysis, here follows a ground-breaking proposal for a possible “Table of Houses”, designed for the use of chemists and Harry Potter fans everywhere.


Slytherin – Alkali Metals and Alkaline Earth Metals

The groups on the far left of the Periodic Table, like Slytherins, are easily excited. It takes very little to set ‘em off. In particular, they react extremely aggressively with the following:

Gryffindor – Halogens

These are useful occasionally, but in general they are pretty harmful – especially in high doses. They are particularly clique-y, and tend to travel in pairs. Very competitive amongst themselves.

Ravenclaw Transition Metals

These are very impressive and shiny at first glance, and pretty strong. They generally need some sort of catalyst to force them to change their behaviour. They are reliable and useful in day-to-day life. 

Hufflepuff Noble gases

These are always . . . around. They know everyone, but they are so laidback they never seem to get in any kind of conflict. They just kind of, you know, hang out.

Additional categorisations:

Professor Albus Dumbledore – Hydrogen

These get involved with everything and everyone. They can be problematic but they are generally needed, and keep everything running smoothly. Works closely with the following: 

Professor Minerva McGonagall – Nitrogen and Oxygen groups

These are the catalysts that get things going. They are essential for life, and everything would fall apart without them.

Giant Squid – Lanthanides and Actinides

These are very mysterious. You hear a lot about them, but they never seem to do much. It’s never really made clear where they came from. They can’t survive in air, generally.

Durmstrang – Boron group

These can bond with some Gryffindors/Halogens (especially those with bushy hair and high intelligence) but may react explosively with others. They all look very similar physically, and while they seem tough, they are surprisingly soft.

Beauxbatons – Carbon group

These are silvery and beautiful. Very stable, and a lot stronger than they look. They often gather huge numbers of followers. Very adaptable.

It is obvious that the Periodic table divides up easily, logically and completely, absolutely naturally into the fictional universe of the Harry Potter series. This discovery has vast potential in and out of classrooms, perhaps as a Chemistry study aid or as a new form of insult. “Urgh, you’re such an Alkaline Earth Metal!” people might soon say, in the same way they would accuse someone of acting like a Slytherin, or a Giant Squid.

Excuse the lack of modesty, but this may even herald the beginning of a new era and a startlingly original way of thinking. Maybe this day will be recorded for years to come as the beginning of . . . Pop Culture Science.
