Atoms are very small. They have a radius of around 1 × ... as the number of electrons and protons are equal in a neutral atom, chlorine also has 17 electrons. The relative mass of a nucleus ...
A new technique uses glowing molecules, laser light and microscopes to measure distances as minuscule as 0.1 nanometres – the width of a typical atom ...
The smallest of those distances was just 0.1 nanometres – the width of a typical atom. The fluorescent ruler also gave accurate measurements up to about 12 nanometres, meaning it had a broader ...
The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...
Fortunately, the Atom isn't just a cute controller ... I have large hands, and small controllers tend to cause cramps after long periods. However, I found that the Atom's button layout meant ...
