What is the emission of electrons from a metals surface when light of a certain frequency shines on it?
photoelectric effect
Is it possible for two metals to have the same emission spectrum?
No. It is not possible for two metals to have the same emission spectrum. For metals to have the same emission spectrum, they would need for their electrons to have duplicate orbitals. That would be impossible due to the exclusion principle.
What is an electron emission?
The process in which an electron emit from metal surface into surrounding is known as electrons emission
What is threshold wavelength?
The greatest wavelength of radiation for a specified surface for the emission of electrons.
How metals conduct eletricity?
There are free electrons on the surface of a metal and their movement on surface is the conductance of electricity.
The shiny surface of metals have most to do with?
The looseness of electrons in metal atoms.
What kind of metals can be quantified by atomic emission spectrometry?
Atomic emission spectrometry is limited to alkali metals.
Are alkali metals suitable for photo electric emission?
yes alkali metals are suitable for photo electric emission
What are the differences between thermionic emission and evaporation?
Thermionic emission occurs when electron leaves the surface of metals while evaporation occur in liquid when strong electron gain energy and escape the liquid surface in gaseous form
What is the phenomenon in which electrons are emitted from a metals surface when light of a certain frequency shines on it?
Photoelectric phenomenon
When nonmetals and metals react which atom electrons?
Metals loss electrons and nonmetals gain electrons.
Does beta radiation results in the emission of electrons?
In beta radiation, an emission of electrons can occur due to beta decay. A neutron can disintegrate into protons and electrons.
