All elements heavier than nickel are only synthesized in supernova explosions, and are therefore relatively rare. Gold isn't that rare compared to many other elements, but it's regarded as intrinsically valuable, and so people tend to hoard it.
(Lead is even heavier than gold, so why isn't it expensive? Well, lead has a number of exceptionally stable isotopes you get to lead by a lot of decay chains from even heavier elements, so it's more common than its atomic weight might suggest.)
Boron is considered to be a relatively rare element on Earth, with an abundance of about 0.001% in the Earth's crust. However, it is found in various minerals and compounds, and is an essential nutrient for plants.
No, phosphorus is not a rare earth element. Rare earth elements are a group of 17 elements in the periodic table, while phosphorus is a non-metallic element commonly found in nature.
Gold is considered a rare element on Earth, with an estimated abundance of about 0.004 parts per million in the Earth's crust. It is typically found in small quantities in various types of rocks and is often mined using advanced extraction techniques.
Gold makes up about 0.005 parts per million of the Earth's crust, which is equivalent to about 0.0005%. It is considered a relatively rare element in the Earth's crust.
Hydrogen is the most abundant element in the universe and is not rare on Earth. However, it is rarely found in its pure form as a gas on Earth due to its lightness and tendency to escape the atmosphere. Instead, it is most commonly found in compounds such as water and hydrocarbons.
Vanadium is considered a relatively rare element in the Earth's crust, with an abundance of about 150 parts per million. It is typically found in certain minerals and as a trace element in fossil fuels.
iridium
No, hassium is not a rare earth element. It is a synthetic element that is part of the periodic table, with the symbol Hs and atomic number 108. It is a highly radioactive element and is not found naturally on Earth, being produced artificially in laboratories.
Gold is a naturally occurring element, meaning it is not manmade. Gold is formed in the Earth's crust through geological processes over millions of years.
No, selenium is not a rare earth element. It is a nonmetallic element that is commonly found in the earth's crust and is used in various industrial applications. Rare earth elements are a group of 17 elements that are found in limited quantities and have unique properties.
Neon is an element found in the form of a gas. It is a rare gas that is found in the Earth's atmosphere.
One element that is not a major element of the Earth's crust is gold. Gold is a precious metal that is considered rare in the Earth's crust, making up only a small fraction of its composition.
Boron is considered to be a relatively rare element on Earth, with an abundance of about 0.001% in the Earth's crust. However, it is found in various minerals and compounds, and is an essential nutrient for plants.
No, phosphorus is not a rare earth element. Rare earth elements are a group of 17 elements in the periodic table, while phosphorus is a non-metallic element commonly found in nature.
Gold is an element and is found in its pure form in the Earth's crust. It is not made from any other substances but occurs naturally as a rare metal.
Promethium is the rarest naturally occurring rare earth element in the lanthanide series. It is radioactive and not found in significant quantities in the Earth's crust, making it one of the least abundant elements on Earth.
No, germanium is not a rare earth element. It is a metalloid in group 14 of the periodic table, along with carbon, silicon, and tin. Rare earth elements are a group of elements found in the lanthanide series of the periodic table.
