Explanation: you take the # of molecules and divide it by avagadros number which is 6.022141 x 10^23
Electrons cannot be located between levels except when they are in the process of moving.
The limitation of the maximum number of electrons in a given energy level can be used to account for the periodic recurrence of properties as the number of electrons increases.
Explanation:
- The Bohr's model of the atom is based on quantum mechanics.
- He suggested that electrons are contained in specific spherical orbits around the nucleus.
- The orbits are also known as shells or energy levels.
- The maximum number of electrons that can be contained by an energy level is 2n².
- An electron in an energy level has a definite amount of energy associated with it at that level.
- Electrons can undergo transitions from one level to another.
