Briefly explain how electrons are distributed in different shell according to Bhron - Burry Scheme

Solution

The Bohr-Burry scheme is a modification of the Bohr atomic model that explains the distribution of electrons in different shells. According to this scheme:
  • The first shell, closest to the nucleus, can hold up to two electrons.
  • The second shell can hold up to eight electrons.
  • The third shell can hold up to 18 electrons.
  • The fourth shell can hold up to 32 electrons.

The distribution of electrons in these shells follows the "aufbau principle," which states that electrons occupy the lowest available energy level before occupying higher levels. This means that electrons fill up the shells closest to the nucleus first, before moving to higher energy levels.

For example, the first shell can hold up to two electrons, so it will always be filled first before any electrons move to the second shell. The second shell can hold up to eight electrons, so it will always be filled before any electrons move to the third shell, and so on.

In summary, the Bohr-Burry scheme describes how electrons are distributed in different shells based on the number of electrons each shell can hold and the aufbau principle, which governs the order in which electrons fill up these shells.
