Software testing is verifying if a software meets the customer's requirements; if it has high quality; if it is bug free and if it is fit for use. Testing is important because it ensures that the product delivered is defect free which in turn emphasizes higher quality and proves to be cost effective.

Atoms are composed of three main particles called electrons, protons and neutrons. We know that, the electrons are negatively charged particles whereas protons are positively charged and neutrons have no charge.

Hence, as the number of electrons and protons are equal and they are oppositely charged, the atom will have no charge as their charges cancel each other.
