Chemistry Questions

Liquid sodium is being considered as engine coolant.

One atomic mass unit (AMU) is equal to the one-twelfth the mass of one carbon-12 atom.

Bond breaking is an endothermic process.

Hence, bond breakage needs an amount of energy and uses some energy based on the strength of the bond to break the bond.

The principal quantum number is the property of an electron which determines the energy of electron and the distance of electron from the nucleus of an atom.

Radon gas is a source of natural groundwater pollution.

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.
