This article presents a personal answer to the question “What is chemistry?”, set out in terms of six propositions. These cover “pureR
All of these reactions and compounds occur because metals and nonmetals share fundamental building blocks. Proton, neutrons and electrons all exist in different numbers in a molecule, and the combination of these three factors determines which element is which. ...
Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur ...

There are two reasons for the difference between mass number and isotopic mass, known as themass defect: Theneutron isslightlyheavierthan theproton. This increases the mass of nuclei with more neutrons than protons relative to the atomic mass unit scale based on12C with equal numbers of protons ...
The Russian Joint Institute for Nuclear Research in Dubna has been the nucleus of the collaboration that produced the new elements Oganessian’s lab is in Dubna, two hours’ drive north of Moscow. To get there means driving down a single-lane highway that cuts straight through a sea of pin...
To find the approximate radius of a carbon nucleus that has six protons and six neutrons, we can follow these steps:Step 1: Determine the number of nucleons The total number of nucleons (A) in the nucleus is the sum of the numb
