When materials are compressed, their atoms are forced into unusual arrangements that do not normally exist under everyday ...

Dot and cross diagrams help us to model when ions are formed from atoms. Here’s an example using sodium and chlorine. They form ions which bond to form sodium chloride. 2. Work out how many electrons ...

The Möbius strip, with its fascinating structure, was first discovered by August Ferdinand Möbius and Johann Benedict Listing in 1858 1. Interestingly, in his review paper on Möbius molecules, Herges ...

For example, the atomic number of sodium is 11. Every sodium atom has 11 protons and 11 electrons. It has 11 positive charges and 11 negative charges. The mass number of an atom is its total number of ...
