Question

What are discrete orbits ? How are we electrons distributed in different in orbit /shells ? Explain with a well labelled diagram .​

Answer 1

Explanation:

By now, we know that, in an atom,  electrons revolve around the nucleus while protons and neutrons are inside the nucleus. The question is, how do electrons revolve? Do they move randomly? Or do they follow a specific route? How are they arranged? The answer to these questions is Electronic Configuration. Let’s learn about the arrangement of electrons around the nucleus.Neils Bohr gave the planetary model of an atom. He was the first person to suggest the periodicity in the properties of the elements. “Bohr atomic model” forms the basis of the electronic structure of an atom. He was the person to describe the arrangement of electrons (electronic configuration) in different orbits/shells.

He proposed that electrons are distributed in circular electronic shells (orbits). These electrons revolve in the orbits around the nucleus from a fixed distance. In this topic, we will learn more about the electronic configuration of different elements.

What are discrete orbits ? How are we electrons distributed in different in orbit /shells ?

$\large{\underbrace{\sf{\red{Required \:answer:}}}}$

Discrete orbits are those orbits where electrons remain stable. As long as, electrons remain in these orbits, they do not radiate energy. Discrete orbits are also known as energy shells or energy levels.

The Arrangement of Electrons in Different Orbits:-

The shells begin from the centre and gradually move outwards. So K shell will always have minimum energy. Similarly, L shell is a little away from nucleus so it will have higher energy than K shell. The outermost shell will have maximum energy.
