Answer:

Task 1:

1. The abundance of the chemical elements is a measure of the occurrence of the chemical elements relative to all other elements in a given environment.

2. The relative abundance definition in chemistry is the percentage of a particular isotope that occurs in nature.

3. Percent abundance is the percentage amount of all naturally occurring isotopes of an element.

Task 2:

Crust- Oxygen and Silicon have the most abundance with Oxygen having the most.

Hydrosphere- Hydrogen and Oxygen have the most abundance with Hydrogen having the most.

Troposphere- Nitrogen and Oxygen have the most abundance with Nitrogen having the most.

Task 3:

Potassium is part of the hydrosphere because Potassium readily dissolves in water during weathering of potassium-bearing minerals and enters the hydrosphere for a long time.

In the Troposphere the last 1% is made of argon, water vapor, and carbon dioxide.

I had to do some investigation for this but I hope this helps :)
