Answer:
It is equal to Avogadro's number (NA), namely 6.022 x1023.
Answer:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
The atomic mass number of the unknown nucleus is 128.
The relationship between the radius of the nucleus r and the atomic mass A is given by
If we assume that the nucleus is a sphere, the volume V is
let the volume of the nucleus having atomic mass number of 64 be V, then the volume of the unknown nucleus having atomic mass number A is written as
Thus, we find that the atomic mass number of the unknown nucleus is A=128
