Where in the earths crust must a mineral occur?
A mineral must occur in the Earth's crust, which is the outermost layer of the Earth. This layer extends from the surface down to about 50 kilometers deep. Minerals are typically formed through geological processes in the crust, making this layer the most common place to find them.
Which two actinides occur naturally?
Uranium and thorium are the two actinides that occur naturally in the Earth's crust. They are found in low concentrations and have important roles in various nuclear reactions and processes.
Do magnetic minerals occur naturally?
Yes, magnetic minerals occur naturally in the Earth's crust. These minerals can be found in various forms, such as magnetite, lodestone, and hematite, and possess magnetic properties due to their composition of iron and other elements.
How many elements occur natural?
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
Where is mendelevium commonly found in nature?
Mendelevium is a synthetic element that does not occur naturally in the Earth's crust. It is primarily produced in laboratories by bombarding other elements with high-energy particles.
Most of the actinides occur naturally in the earths crust?
no they do not
Are most of the actinides occur naturally in earth's crust?
No, most of the actinides do not occur naturally in Earth's crust. Actinides are a group of elements that are mostly synthetic or man-made through nuclear reactions. Only a few actinides, like uranium and thorium, occur naturally in significant quantities in the Earth's crust.
In which form do many minerals occur naturally on the earths surface?
Many minerals occur naturally on the earths surface in rock form
What state do almost all metals occur in naturally?
Metals typically occur in their native form, meaning they are found naturally as pure elements in the Earth's crust. This is because metals are stable in their metallic form due to their high reactivity with other elements.
How many elements start naturally in nature?
how may elements occur naturally in nature

Do most actinides occur naturally in the earth's crust?
Yes
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
How many known elements are there on earth are naturally made?
There are 92 naturally occurring elements on Earth.
Which element is a member of the rare earth elements?
There are seventeen of these. Please see the link.
