New Elements Describe why "new" elements (man-elements) are created‚ or why do we benefit in creating them? Elements are the building blocks of which all things are composed. The elements of Earth are made up of atoms. All atoms possess a nucleus of positively charged protons as wells and neutrons which are neutrally charged. Surrounding the nucleus is a low density area containing negatively charged electrons that are equal to the number of protons within the nucleus. The number of protons within
