Discussion the basic idea Dielectrics are insulators, plain and simple. The two words refer to the same class of materials, but are of different origin and are used preferentially in different contexts. Since charges tend not to move easily in nonmetallic solids it''s
Atomic spectra - ITP
Atomic spectra Light emitted or absorbed by single atoms contributes only very little to the colours of our surroundings. Neon signs (or other gas discharge tubes) as used for advertising, sodium or mercury vapour lamps show atomic emission; the colours of
Electronegativity and Polar Covalent Bonding - dummies
Electronegativity is the strength an atom has to attract a bonding pair of electrons to itself. When a chlorine atom covalently bonds to another chlorine atom, the shared electron pair is shared equally. The electron density that comprises the covalent bond is loed halfway between the two atoms. But what happens when the two atoms […]

Metal Strength and Stiffness: What’s the Difference?
Words like strength and stiffness are so similar that it seems easy to not know the difference. Unless people are in the steel industry, I’d doubt that they would know the difference. It’s pretty interesting thinking about how the terminology changes depending on the

Atoms and Elements - Mountain View College
Electrons remain in an atom because of their attraction to the protons’ positive charge, but they are not as tightly associated with the atom as either protons or neutrons. Electrons are complied particles because they have a lot of space to occupy in an atom, and yet they are also tied to a specific area within that atom.

Review of Modern Physics
Albert Einstein explained this experiment by postulating that the energy of light is quantized. He assumed that light consists of individual particles called photons, so that the kinetic energy of the electrons, K.E= p 2 /2mequals the energy of the photons, E ph, minus the energy, qF M, required to extract the electrons from the metal.
