Proteins functions as a source of energy and to control the rate of reactions and regulate cellular process.
Protons along with electrons and neutrons are the building blocks of atoms. One can obtain a proton by stripping an electron from a hydrogen atom because hydrogen consists of one proton and one electron. ... At Fermilab, we take hydrogen and add an extra electron.
The atomic structure of an atom that is stable and unreactive would first be that its valence shell is full, it is a happy atom. They do this by losing, gaining or sharing their electrons. This makes them stable. It is also a Noble gas, noble gases are unreactive!
