Itch: The Explosive Adventures of an Element Hunter by Simon Mayo

Thrills. Danger. And world domination. Itch is as action-packed and suspenseful as a middle-grade novel can get.

Fourteen-year-old Itchingham Lofte, nicknamed Itch, has an unusual passion: collecting specimens of every element in the periodic table. So what if that means hes had a few ... mishaps? But when he gets his hands on a suspiciously warm rock made of a new, previously unknown element, things really begin to explode. Soon, a malevolent teacher, an evil-doing corporation, and a top-secret government agency are all after Itch. Can his science know-how keep him one step ahead of everyone..and help him stay alive?

Cover and jacket flap feature augmented reality animations via a free downloadable Itch app!

Most Explosive Elements on Earth

Alkali metal

Today, we are meeting potassium, the chemical element with the atomic number 19 and the symbol K from Latin, kalium , which was taken from the word for "alkali", which in turn came from Arabic for "plant ashes". The English name, "potassium", is derived from the word "potash". Notice the theme for this element's names? Elemental potassium is soft and silvery-white in colour and has one more electron than argon , an element that we know is extremely stable. This easily-lost electron makes elemental potassium extremely reactive, like its "little sister", sodium , another highly reactive alkali metal -- a feature that keeps chemists who work with it in top physical condition as they flee for their lives from the resulting explosion and flames. If potassium was a human, it would be court-mandated to take anger management classes.

Element 55 in our International Year of the Periodic Table series is caesium. Caesium is used in atomic clocks and is the most reactive metal in the periodic table. Caesium is the element most commonly used in atomic clocks, which provide the most accurate times. Since , the second has been defined in reference to electron transitions in a caesium atom. Caesium atomic clocks in satellites help GPS and mobile phone networks function. The group 1 metals increase in reactivity as you descend the group, and caesium is the most reactive of these metals — and the most reactive in the periodic table. In the meantime, Periodic Videos have a video showing the reaction of caesium with water.

It's fun to watch chemistry labs explode on video, but you know what's even more fun? Watching a chemistry experiment in action, with a good explanation of what's going on. That's science at its most awesome. Here are ten of our favorite chemical reactions caught on video — which also include excellent commentary on what you're seeing. So how do you get hydrogen to pair up with oxygen? One way is demonstrated here.

1. Headline Elements: Be Bold and Attract Attention

Take landing pages, for instance. In other words, landing page creation is a bit like chemistry. But which elements do you need? Then, we divided each section into elements to help you optimize the key components of your page. Of course, not every landing page will have room for every element—your page will look different depending on whether the goal is subscribing to your email list or enrolling in your paid course, for instance.

Alkali metal , any of the six chemical elements that make up Group 1 Ia of the periodic table —namely, lithium Li , sodium Na , potassium K , rubidium Rb , cesium Cs , and francium Fr. The alkali metals are so called because reaction with water forms alkalies i. Sodium and potassium are the sixth and seventh most abundant of the elements, constituting , respectively, 2. The other alkali metals are considerably more rare, with rubidium, lithium, and cesium, respectively, forming 0. Francium, a natural radioactive isotope , is very rare and was not discovered until The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. Like the other elements in Group 1, hydrogen H has one electron in its outermost shell, but it is not classed as an alkali metal since it is not a metal but a gas at room temperature.
