The crystalline substances that are found naturally in the earth are known as minerals. There are literally hundreds of minerals on Earth that are used in everything from industrial purposes to consumption.
Rock and minerals are both considered to be natural substances and this is what they have in common.

Argon is found in the air! Argon is present if the Earth's atmosphere at 0.94%
Arsenic is an element so you don't really create it. It is usually refined from iron, nickel, or cobalt sulfides or sometimes found relatively pure in it's crystalline form.
There is said to be about 0.0015% of gallium found in the Earth's crust with no known concentrated supplies of it
Almost every element from hydrogen to uranium (going from smallest to biggest) is found naturally on Earth. Technitium is not found naturally on Earth, it is the exception. The trans-uranic elements are also not found naturally on Earth.
Naturally occurring substances found on earth. They are substances we process into the products we use in our everyday lives. examples. Trees for paper and wood. Stone or rock for building roads. Metal and silicon for making out electronics.

It is a mineral, learned it in science Yep you are absolutely right, its a mineral! thanx!

The halogens are not found naturally in the earth's crust as pure elements because of their extreme reactivity. Because the halogens are close to having completely filled electron shells, they will often react with other substances in order to gain an electron. As an especially noteworthy case, fluorine is the most reactive of the halogens (and elements in general), and will even react with glass. Therefore, the halogens are found naturally as compounds, not pure elements.
because earth does not have the energy to produce plasma
Fluorine is found naturally in Earth's crust!

Silicon is the second most abundant element in the Earth's crust, making up about 28% of its mass. It is commonly found in the form of silicon dioxide (silica) in rocks, sand, and soil. It is also found in many minerals, such as quartz and feldspar.
