Answer:
when electron emit the radiations it means it jumped to the lower energy level from higher energy level.
Explanation:
When electron jump into lower energy level from high energy level it loses the energy.
The process is called 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:
Oxidation half
Ca -----> Ca2+ +2elecyrons
Reduction half
Cl2 + 2electrons ------> 2Cl-
Explanation:
Hi!
The reason for reviewing and replicating work of other scientists is influenced by two factors listed in the answer:
1. An experiment may have had errors that the scientist did not recognize. <u>(unintentional) </u>
2. The results of individual scientists may be influenced by bias. <u>(intentional)</u>
<em>Personal motivations may often influence a scientist to manipulate the results to best suit his/her hypothesis, consequently leading to scientific fraud. </em>
While other options listed are elements of the scientific method, they are not the reasons behind the review and replication of a scientist's work by others.
Over here a lead weight moved from sea level to the top of a mountain high and a sample of chlorine gas compression the density increases for the substances.
Good luck
