When the reversed polarity voltage almost equals the Zener voltage, the electric field in the depletion portion is such strong that it pulls out the electrons from their valance shells. The outermost shell electron that gets enough power from the field will break out from the effect of the moth...
What is the most basic atom in the starting material? Explain. An atom has a small ___ charged core called the nucleus, with ___ charged electrons moving in the space around the nucleus. What are the electrons on the outermost energy level of an atom called? What is an atom that has...
sodium is a very reactive metal which reacts with oxygen and moisture in the air if kept open. to avoid external contact, sodium is stored in kerosene. q2 why sodium is highly reactive? sodium belongs to group 1 which is called alkali metal. having one electron in the outermost shell ...
What are the electrons in the outermost shell of an atom called? Which of the following elements are capable of forming compounds in which the indicated atom has more than four valence electron pairs? That is, which can form compounds with five...
The outermost electrons -- the valence electrons -- are able to interact with other atoms, and, depending on how those electrons interact with other the atoms, either an ionic or covalent bond is formed, and the atoms fuse together to form a molecule. Electron Shells Every element is ...
The crisscross method is a way to determine the chemical formula of compounds by using the valence of the atoms. Atoms have a central core of protons and neutrons, with layers of electrons circling the core in layers called shells. The outermost shell may contain too many or few electrons,...
How is the ionization energy of an element or atom calculated? The fifth row of the periodic table corresponds to what energy level in the atom? What is the overall charge of an atom? How does the energy in the third shell of an atom compare to the energy of an electron i...
Holes are formedwhen electrons in atoms move out of the valence band(the outermost shell of the atom that is completely filled with electrons) into the conduction band (the area in an atom where electrons can escape easily), which happens everywhere in a semiconductor. ...
composed of crystals made of several materials. To better understand how semiconductors work, users must understandatomsand howelectronsorganize themselves within the atom. Electrons arrange themselves in layers called shells inside an atom. The outermost shell in the atom is known as a valence shell...
In semiconductors, the valence band, which contains the outermost electrons, is separated from the conduction band, where electrons can move freely, by a relatively small energy gap called the band gap. The temperature, impurities, or application of an electric field are all ways...
