What is the electron configuration of an element with atomic number 15? What is the atomic number of nobelium? What is the atomic number of copernicium? What is an atom that has more protons than electrons? What is the atomic number for xenon?
We present a simple method for the quantitative analysis of light elements, H, C, N and O, in thin, self-supporting low Z films with MeV protons in one run. Proton-proton scattering is utilized for the detection of hydrogen and backscattered protons are simultaneously analyzed for detecting ...

The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. About sixteen radioactive isotopes of lead are known also. A radioactive isotope is one that breaks apart and gives off some form of radiation....

What is an atom that has more protons than electrons? What element has 10 electrons? What element has 13 electrons? What is the most reactive non-metallic atom? Which electrons are most responsible for the properties of an atom? What radioactive element has the lowest atomic number?
In Table 3, we exemplify some of the results of such computer simulations, normalised to 1013 neutrons produced by the source (23 MeV protons on a thick Beryllium target) and injected in the Activator with the geometry described in Table 6. We have chosen a Molybdenum salt Na2MoO4 (other ...
