Distribution of Electrons in Orbits or Shells
Electronic distribution of various orbits or energy levels can be calculated by the formula 2n2. Here, ‘n’ denotes the number of orbits.
The number of electrons in the K shell (1st orbit) can be calculated by 2n2= 2 × 12 = 2. Thus, the maximum number of electrons in 1st orbit = 2
Similarly, The number of electrons in the L shell (2nd orbit)= 2 × 22 = 8. Thus, the maximum number of electrons in the 2nd orbit = 8
The distribution of electrons in the various orbits is discussed in the image below,
Bohr’s Model of an Atom
Bohr’s Model is an atomic model proposed by Danish Physicist Niels Bohr in 1913. According to this model, in an atom, the electrons revolve around the nucleus in definite energy levels called orbits/shells. This model provides a basic understanding of the concept of the atom and its constituents.
Let’s learn more about Bhor’s Atomic Model, its limitations, and others in detail in this article.
