What are all of the requirements for a thunderstorm to form

Hot air, cold front, moisture

Explanation:

According to its definition, an electrical storm is a local storm formed by a cumulonimbus, accompanied by lightning and thunder

In order a storm is formed, the following elements are needed: hot air, cold front of air and moisture

Storms are formed if there are hot and humid conditions, but are more frequent during springtime and summer

To form that kind of storm  a hot air humidity is necessary.

Then that steam goes up to the atmosphere.

So, the atmosphere becomes unstable because of the hot air with the contact of fresh air.

Sudenly, Storms can form with the air masses.

To be a thunderstorm is necessary  the air hot and fresh growing up too fast, and the lightning strikes occur when ice or snow particles begin to fall of the clouds. And energy of those airs makes the difference in charge between the particles.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
