Photo electrons. So current due to these photo electrons is named as photo electric current.
An atom that loses or gains electrons is called an ion. When an atom loses electrons, it becomes positively charged and is called a cation. When an atom gains electrons, it becomes negatively charged and is called an anion.
the electron microscope is called that because it uses beams of electrons to accurately measure distances on atomic scales
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
Electrons: Irish physicist George Johnstone Stoney (and later, successfully, by George F. Fitzgerald)Protons: William Prout called them protyles, Ernest Rutherford suggested proton.
The outer electrons of an atom are called valence electrons.
The current atomic model is called the quantum mechanical model. It is named that because it incorporates the principles of quantum mechanics to describe the behavior of electrons in atoms, including their wave-like properties and probability distributions.
These electrons are called "outershell electrons" or "valence electrons."
the electrons in the outermost shell of an atom are considered to be the valence electrons.
In 1897, a British scientis named J.J. Thomson.
The electrons located in the outer shell are called "valence electrons".
The electrons in the outermost shell is called as valence electron. These electrons are free and they are involved in bonding reactions.
