Answer:
The transition from lower energy level to higher energy level require a gain of energy.
Explanation:
When transition occur from lower energy level to higher energy level require a gain of energy. Electron could not jump unto higher energy level without gaining thew energy.
When electron jump into lower energy level from high energy level it loses the energy.
For example electron when jumped from 2nd to 3rd shell it gain energy and when in return back to 2nd shell from 3rd shell it loses energy.
The process is called excitation and de-excitation.
Excitation:
When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits.
De-excitation:
When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum.
Answer:
A D F
Explanation:
Its right but its not in order But its A D and F
This is the same as its freezing point
hope this helps
We see that is the <em>structure </em>of graphite it possess these attributes.
Graphite
Option A
<h3>Electricity</h3>
Generally, he conduction of electricity is do by elements with free talent electron after bonding.
Therefore, it is save to say that the <em>solid </em>that possess the attributes that allows for conduction will end up conducting.
Hence, we see that is the <em>structure </em>of graphite it possess these attributes.
