beryllium
No because it is not an element. It is a mixture of 3 aromatic isomers found in crude oil.
Einsteinium is an artificial element; it is prepared as a compound, probably as an oxide or as a compound with halogens.
Sulfur is a chemical element (S) and doesn't contain any other mineral.
The term means an element, such as carbon or oxygen, is found in a compound or in an environment.
the answer is that it occurs as a compound, not an element

beryl
The Classification of beryllium is a metal.
It is an element, and can be found on the Periodic Table as Al.
Beryllium is a naturally occurring element, found in the Earth's crust, and is the fourth lightest element in the periodic table. Beryllium is found naturally in its elemental form and in a variety of compounds, such as beryl and bertrandite. Beryllium is also found in coal, soil, and volcanic dust. Beryllium is a very rare element, making up just 0.0002 percent of the Earth's crust. Beryllium is a naturally occurring element due to several factors. Firstly, beryllium is extremely abundant in stars and supernovae, which produce energetic particles that are able to travel vast distances through space and eventually become trapped in the Earth's crust. Additionally, beryllium is a very stable element, and its compounds are also very stable, which increases the likelihood of its natural occurrence. The following are the most common sources of naturally occurring beryllium: Beryl: the most common ore of beryllium, found in granites, pegmatites, and high-temperature hydrothermal veins Bertrandite: a beryllium-containing mineral found in beryllium-rich pegmatites Coal: a combustible sedimentary rock containing trace amounts of beryllium Soil: beryllium is found in soils around the world, particularly in volcanic regions Volcanic dust: beryllium is released into the atmosphere during volcanic eruptionsIn conclusion, beryllium is a naturally occurring element due to its abundance in stars and supernovae, its stability, and its presence in a variety of compounds and materials found in the Earth's crust.
Beryl can be found in alluvial deposits from erosion out of pegmatite veins. This is the easy way, sorting through sand and gravel. The hard way is to attack the granitic pegmatite with tools and see what's inside.
Helium is found as a mono atomic element. It is not found as a mineral.

No, but it is an element found in many minerals.
Copper is an element which can be found in rocks, or it can be found in a relative pure state in nature called native copper, which is a mineral.
