When the outer electron shell is full in an element, this creates a Noble gas.
<u>Explanation</u>:
Noble gases are the elements that belong to group 18 in the periodic table. Noble gases are also called as inert gases. The outermost shell of the noble gases are fully filled by electrons. Due to this the noble gases don’t react with any other elements and remain isolated.
There are 6 noble gases in the periodic table. They are helium (He), Argon (Ar), Neon (Ne) Krypton (Kr), Radon (Rn) and Xenon (Xe). Noble gases conduct electricity. They are fluorescent, odorless and colorless. Noble gases are used a maintain stable elements in a constant and safe environment.
The correct answer is - limestone.
On the image, it seems that we have a representation of rock formations in a cave. They are evidently weathering. According to the manifestation of the weathering, the color of the rocks, and that it is most probably a cave, the chances are mostly likely that it is a limestone.
The weathering appears as a result of the water. The limestone is a sedimentary type of rock, thus it doesn't have strong structure. The water is able to gradually penetrate through it, making holes in it, and little by little weather it. In this way we have the formation of the water reservoirs, springs, cave systems.
