<h2>
Answer: # of neutrons = 9</h2>
<h3>
Explanation:</h3>
# of neutrons = mass number - atomic number
= 17 - 8
= 9
<h3>∴ number of neutrons in an atom of oxygen of mass number 17, is 9.</h3>
Answer : 10 plague hearts are there in one map at a time in state of decay 2
Explanation : The State of Decay 2 consists of 10 Plague Hearts which one needs to destroy and they are placed on randomly dotted areas around the map inside a searchable location on it.
With each heart that one destroys, the remaining other ones become a little bit tougher and are more heavily guarded by the undead people.
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>
