The type of bond formed when electrons are shared between atoms.

What is covalent?

200
The minimum amount of energy required for a reaction to occur is known as this.
What it is activation energy?
200

A substance when added to water releases H+. This results in the forming of a lot of H3O+ molecules.

What is an Arrhenius acid?
