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 ...
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 ...
Electrons are best known for carrying electric ... by Jean-Charles Peltier in 1834 — some sixty years before the discovery of the electron. The goal in solid-state refrigeration is to create ...
