In the universe, protons are abundant, making upabout halfof all visible matter. (a) Pick any one of the first 10 elements that you would like to build and state its symbol. Many other rare types of decay, such as spontaneous fission or neutron emission are known. and the term oxidation number is nearly synonymous. Ceriumis a chemical element with atomic number58 which means there are 58 protons in its nucleus. Neutrons are in every atom (with one exception), and they are bound together with other neutrons and protons in the atomic nucleus.
