excitation
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
Electrons in the outermost principal energy level are called valence electrons.
Electrons absorb energy to make electrons move from an lower energy level to a higher energy level. This energy is released as some form of e-m radiation when the electron moves from the higher level to a lower energy level.
valence electrons
"Excited", or in an "excited state".
These electrons are called "excited".
No, electrons must absorb energy in order to move to a higher energy level. They release energy when they move to a lower energy level.
protons move to a higher energy level protons move to a lower energy level electrons move to a higher energy level electrons move to a lower energy level
More energy have the electrons in the second level of energy.
state in which electrons have absorbed energy and "jumped" to a higher energy level
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
LED diode:when certain amount of voltage is applied to LED diode the electrons which are present in lower energy level jumps in to higher energy level after certain time the electrons in the higher energy level again jumps in to lower energy level .while jumping from higher energy level to lower energy level electrons emits energy in the form of light(visible or invisible)
Nitrogen has five electrons on the outer level.
Electrons in the outermost principal energy level are called valence electrons.
Valence electrons
The highest energy level is called the "electronegativity".
Electrons absorb energy to make electrons move from an lower energy level to a higher energy level. This energy is released as some form of e-m radiation when the electron moves from the higher level to a lower energy level.
