In diesel engines, the chemical energy in the fuel is changed to heat energy, causing the pistons to expand via mechanical energy. The mechanical energy is finally converted to kinetic energy, which is observed as the movement of the vehicle.
During this process. A. Solid turns directly into a Gas.
<span>The type of bond that a
Phosphorous pentachloride have is an Ionic Bonding. It is a form of chemical
bond that encompasses the electrostatic attraction between oppositely charged
ions which serves as the primary interaction happening in ionic compound. Phosphorus
has 5 valence electrons and Chlorine has 7 valence electrons. Phosphorus contributes
1 electron to each chlorine and all the 6 achieve 8 electrons in the outer
shell thus creating an ionic bond.</span>
Answer:
if u know the number of electrons u also know the number of protons present in the atom.
When an electron in a quantum system drops from a higher energy level to a lower one, the system<u> emit a photon.</u>
<u />
The energy of the electron drops when it transitions levels, as well as the atom releases photons. The emission of the photon occurs as the electron transitions from an energy state to a lower state. The photon energy represents precisely the energy that would be lost when an electron moves to a level with less energy.
When such an excited electron transitions from one energy level to another, this could emit a photon. The energy drop would be equivalent to the power of the photon that is released. In electron volts, the energy of an electron, as well as its associated photon (emitted or absorbed) has been stated.
Therefore, when an electron in a quantum system drops from a higher energy level to a lower one, the system<u> emit a photon.</u>
