Q. Illustrate modern atomic model of De Broglie?

1. Electrons inhabit the space surrounding the nucleus and can exist in several discrete principal energy levels each designated by one of the principal quantum numbers (n) that are the integers 1, 2, 3, 4, etc.

2. Electrons in consecutively higher principal energy levels have greater energy.

3. For the reason that of interactions among electrons each principal energy level consists of energy sublevels that have slightly different energy values. These sublevels are elected by the letters s, p, d, and f in order of increasing energy. The primary principal energy level (n = 1) has only one sublevel (s). The subsequent principal energy level (n = 2) consists of two sublevels (s and p). The next-to subsequent principal energy level consists of three sublevels (s, p, and d) and the fourth consists of four sublevels (s, p, d, and f).

4. Every energy sublevel consists of one or more orbitals each of which can contain two electrons. A s sublevel has one orbital a p sublevel has three orbitals a d sublevel has five orbitals and an f sublevel has seven orbitals. All of the orbitals in the similar sublevel are of equal energy.

5. Atomic orbitals are sections of space in which there is a high probability (90 percent) of finding an electron. Apart from for s orbitals the orbitals aren't spherical in shape. Dissimilar Bohr's atomic model electrons aren't in specifically defined orbits. As an alternative they can be anywhere within the orbital and there is a 10 percent chance that the electron will be located outside the orbital.
