# Electrons Shells Configuration MCQs Questions and Answers

## Electrons Shells – Definition

As we know, the topic of electrons shells is purely related to the the concept of atomic structure . All the atoms consists of 3 basic particles called Electrons (Negative Charge), Protons (Positive Charge) and Neutron (No Charge). The Protons and Neutrons are inside the Nucleus (Centre Part of an Atom). The electrons are moving in the Shells / Orbits / Rings
