Life would be very different without metals. No cars, no electrical goods, no saucepans, and only the lamest of hippie jewellery. Like all atoms and elements, the properties of metals come down to the ...

A research team has discovered clusters of aluminum atoms that have chemical properties similar to single atoms of metallic and nonmetallic elements when they react with iodine. The discovery opens ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

This episode is from WHRO’s Spotlight Earth series. Watch this video to learn about matter. In this Spotlight Earth episode, you will explore the fundamental building blocks of the universe, including ...

Qubits, the building blocks of quantum computers, can be made from many different technologies. One way to make a qubit is to trap a single neutral atom in place using a focused laser, a technique ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

The chemical identity of individual atoms on a surface can now be determined using an incredibly powerful atomic force microscope. It means that scientists can now look at a mixed material and pick ...

Diatomic elements hate to be alone — so much so that they just aren't found as single atoms. Instead, they're always two atoms of the same pure element bonded together. It's right in the name: Di- ...

While one mole of any element has the same number of atoms, one mole of different elements has different masses. This is where the concept of molar mass comes in. The molar mass of an element is the ...
