Iii) Shells are filled with electrons in a stepwise manner i. e., the outer shell is not occupied with electrons unless the inner shells are completely filled with electrons. The following are the rules to write the number of particles in different orbitals: - The formula 2n^2 gives the accommodation of the maximum number of electrons in each shell, n=1, 2, 3, 4 for K=2, L=8, M=18, N=32. The chapter will take you through important topics like fundamental constituents of an atom, different models of an atom, distribution of electrons, valencies, atomic number, and mass number. For example, the atom of oxygen has six valence electrons. Chapter 4 the structure of the atom answer key 2022.

Chapter 4 the structure of the atom answer key unit. Question 3: Draw a sketch of Bohr's model of an atom with three shells. When the electron jumps from one energy shell to another, a change in magnitude takes place. The negatively charged particles present in the outermost shell are called Valence Electrons. Therefore, 2 electrons go to K-shell and 8 electrons go to L-shell, thereby completely filling K and L shells.
