The question asks for the name of a very small piece of matter with a negative electrical charge found in all atoms. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom.反馈 收藏
An element is a substance from which only one kind of matter has ever been obtained. The smallest part of an element having the same properties as the element is called an atom. An atom consists of a nucleus, containing electrical charges called protons, and spinning around the nucleus in ...
1.2 For many solid metals –as for example the elemental metals silver (Ag), copper (Cu), gold (Au), aluminium (Al), sodium (Na), tungsten (W) and platinum (Pt) - each atom releases just one electron. These electrons move quasi-freely through the metal. These charge carriers give ri...

Atom RSS Feed Electrical and electronic engineering is the branch of engineering that makes use of electricity. Electrical engineering concentrates on systems for generating and transmitting large electrical currents and converting them into other forms of energy, such as mechanical motion. Electronic engin...
Holes are the same as the lack of electron at a position in an atom. Simplified, electrons are the charge carriers in metals and electrons and holes are in what are called semiconductors. To come into motion charge carriers have to be mobile. Mobility is a highly material-dependent property...
An Example of a Kid-Friendly Explanation Everything in the world is made up of atoms. These are tiny particles made from even smaller particles called protons and electrons. Each of these carries a charge to attract the other. When electrons move from one atom to another, this movement creat...
