Chemistry Questions

Chemical weathering is the process of altering rocks chemically when they are broken down. It includes hydrolysis, oxidation, acid rain, etc...

Covalent bonds are bonds formed between two non metals by sharing of electrons in their outer most orbits for stable.

An ionic bond is formed between two molecules when transfer of valency electrons take place between them. 

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.
