So, do you know which one out of the 118 is the rarest element, or do you at least have a guess?

se the information and your knowledge of science to answer the question.​Thousands of minerals can be found on Earth's surface. Some minerals are very common and can be found at locations all around the world. Other minerals are extremely rare and can only be found in one or two locations on Earth.​Select the mineral that is most likely to be found in many locations around the world, and select the text that best supports the mineral selection.Mineral A forms where vanadium and copper exist together at fumaroles, or openings, on the sides of volcanic mountains. As gases pass through the openings, the mineral forms along the surface of the fumaroles and then washes away when it rains.Mineral B forms under high temperature and pressure around 100 miles below Earth's surface. After forming, it is then brought to the surface through violent volcanic eruptions and is one of the hardest minerals on the Mohs hardness scale.Mineral C is found where silica and oxygen naturally occur and is formed when the silica and oxygen combine. The mineral does not require a specific temperature or pressure to form and is resistant to weathering.
