Elements that occur somewhere on earth are what?
Elements that occur naturally on Earth are called "native elements." These elements are found in their pure form without being combined with other elements. Some examples include gold, silver, and diamond.
Do all the 116 known elements occur naturally on Earth?
No, only the elements up to Uranium (Z=92) occur naturally on Earth. The rest have only been made synthetically, because of their radioactivity which renders them unstable and thus unable to exist naturally. The synthetically made elements are called transuranic elements.
How many naturally occurring elements are found on this planet?
I say there are 92. At school, we were taught that there are 92 naturally occurring chemical elements on Earth. They are all the elements from hydrogen to uranium. However it's a bit more complicated than that. Here's some more detail: There are 2 elements of the first 92 that are so unstable they are not found in nature. Actually minute traces of these have now been detected, I believe. There are 2 elements beyond uranium that do occur naturally as the product of the radioactive decay of Uranium. So, the final total is probably 92. However, it may be anything from 90 to 94, depending on what you include.
Elements past 92 are considered what?
Elements past 92 are considered transuranium elements, which are all synthetic and are created artificially in laboratories. These elements do not occur naturally on Earth.
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.

How many naturally occurring elements are (were) there on earth?
92 are natural occuring, other remaining are man made.
If earth has nearly 4000 mineral which are made from naturally occurring elements?
Yes, Earth has a vast variety of minerals, with around 4000 known mineral species made from naturally occurring elements. These minerals have unique chemical compositions and crystal structures, forming the building blocks of rocks and the Earth's crust. They play a crucial role in our everyday lives, being used in various industrial processes, technologies, and products.

Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
What are the four element of a periodic table?
There are 118 currently known elements though not all are naturally occurring. When you say 4 elements you might mean earth, wind, water and fire which ancient scientist thought made up all matter.
Earth has nearly 4000 minerals which are made from naturally occurring elements.?
That is correct. Minerals are solid, inorganic substances that are composed of one or more naturally occurring chemical elements. They have a specific chemical composition and atomic structure.
How many Kinds of atoms present on the earth?
90 occur naturally - others have been made in nuclear reactors etc
Elements past 92 are considered what?
Elements past 92 are considered transuranium elements, which are all synthetic and are created artificially in laboratories. These elements do not occur naturally on Earth.

Why transuranic element known synthetic elements?
Transuranic elements are known as synthetic elements because they are not found naturally on Earth and must be created in a laboratory through nuclear reactions. These elements have atomic numbers higher than uranium (92) and are generally unstable and radioactive. Scientists have been able to produce transuranic elements by bombarding heavy elements with particles to create new elements.
How many natural elements are there?
Out of the first 92 elements, 1 being hydrogen (H) and 92 being uranium (U), there are 90 that are naturally occurring. Technetium (Tc) and promethium (Pm) are man-made elements and do not have any isotopes occurring naturally.
