The element with 16 neutrons, 15 protons, and 15 electrons isphosphorus. Technically, this is a neutral atom of the phosphorus-31 isotope because the... What element has 2 protons neutrons? Heliumis the second element of the periodic table and thus is an atom with two protons in the nucle...

In a lecture to the Royal Society in June 1808, Davy described how the magnesium he obtained was not pure because of difficulties in removing the mercury entirely from the magnesium. He was, however, able to observe that in air the metal turned into a white powder, gaining weight as it r...

Different radiation qualities, such as protons of different energies, neutrons and alpha particles, have been used for samples irradiation. Thermoluminescent sensitivity to ionizing radiation, dose-response characteristics and relative thermoluminescence efficiency have been evaluated for all radiation qualities...
All magnesium atoms have 12 protons inside their nuclei. Previously, the lightest version of magnesium had 7 neutrons, giving it a total of 19 protons and neutrons — hence its designation as magnesium-19. To make magnesium-18, which is lighter by one neutron, the team started with a...
