which atom is involved in giving your heart energy to beat

Understanding how and why some atoms will readily form bonds while others flatly refuse to do so is at the heart of making and designing new compounds and a problem that Professor David Brown, Emeritus Professor at McMaster University, has spent many years thinking deeply about. Multiple atoms bonded together by sharing of their negative charge is what leads to the formation of solids and liquids. Depending on exactly how many protons each atom has and how fond it is of its surrounding negative charge, atoms may start to share their charge and form what are known as chemical bonds. When atoms start to meet other atoms though, strange things start to happen. Instead, they merge to form a cloud of negative charge around the nucleus, much as the air forms an atmosphere around the Earth. When the electrons are trapped by the nucleus, however, they no longer exist as individual electrons. For electrons, which move much more rapidly than the protons and neutrons in the atom, the positive lure of the proton can be hard to resist and that is why, most stable atoms or elements, have a perfectly balanced complement of protons and electrons. Protons have the same mass as neutrons, but as they are positively charged they will suck up any oppositely charged species, or strongly repel other positively charged ones. The same is not true for the equally-heavy protons and very light, hyperactive electrons. They add a great deal of mass to the atom, but rarely interact with anything else. For chemists, neutrons are typically the least interesting of these – they are the heavy loners of the chemical world. An atom has three parts: protons, neutrons and electrons. Professor David Brown at McMaster University has been developing new models to help teach us the tricks of chemical structure and bonding.Ītoms are complex objects with complex lives.

It is exactly this formation and breaking of bonds that chemists are trying to master in the lab, as innovative new ways to control chemical bonds make it possible to make novel compounds that might hold the key for future pharmaceuticals and high-tech materials. The ability of atoms to form bonds with each other allows the formation of molecules. The making and breaking of bonds lies at the heart of chemical reactions.
