Scientists worked with electricity long before they understood that current was made of electrons. The cathode tube was a prime example. By switching on some voltage, scientists could make ...
Strong interactions between subatomic particles like electrons occur when they are at a specific energy level known as the ...
Scientists at High Energy Stereoscopic System in Namibia have detected most energetic cosmic electrons ever observed after ...
Light isn’t just for seeing—it can also give things a push. When light travels, it carries energy and momentum, which is like ...
The discovery was made by astrophysicists from ... Temperatures this extreme results in electrons not being attached to atomic nuclei, but instead floating around in a so-called ionized plasma.
The question of what protons or neutrons are made up of has an apparently simple answer: quarks and gluons. However, when it ...
The New Zealander had discovered the atomic nucleus in 1911 and further investigations by Bohr led to his quantum model of the atom where electrons travel around the nucleus in certain orbits. When ...
He discovered the atomic nucleus and developed a model of the atom that was similar to the solar system. Like planets, electrons orbited a central, sun-like nucleus. Acceptance of this model grew ...
Whatever his thought process, Mendeleev ultimately arranged the elements according to both atomic weight and valence electrons. Not only did he leave space for elements not yet discovered ...
