Some elements are not naturally occurring because they are created in laboratories through nuclear reactions or particle accelerators. These synthetic elements do not have stable isotopes and decay rapidly, making them difficult to find in nature. Examples include elements beyond uranium on the Periodic Table.
Not all the elements occur naturally; some elements are man-made.
There are 118 known chemical elements, of which 92 occur naturally on Earth. These naturally occurring elements include a variety of atoms, ranging from hydrogen (the simplest) to uranium (the heaviest). While some of these elements are abundant, others are quite rare in nature. Each element consists of unique types of atoms that define their chemical properties.
Some elements found in nature that mainly have radioactive isotopes include uranium, thorium, and potassium. These elements have naturally occurring radioactive isotopes that decay over time, releasing energy in the form of radiation.
No, metalloids are not all man-made. Metalloids are a group of elements on the periodic table that have properties of both metals and nonmetals. Some metalloids, like boron and silicon, are naturally occurring elements.
Yes, a natural isotope can be radioactive. Some natural isotopes have unstable nuclei and undergo radioactive decay to achieve a more stable form. This process involves the emission of radiation in the form of alpha particles, beta particles, or gamma rays.
Not all the elements occur naturally; some elements are man-made.
Most of the naturally occurring elements are metals. These elements are found in the Earth's crust and have various physical and chemical properties. Some examples of naturally occurring metals include iron, copper, and gold.
No. Much of naturally occurring matter consists of mixtures and some of pure elements, neither of which is a compound.
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.

Some examples of naturally occurring blue foods include blueberries, blue corn, and purple potatoes.
The reason why there are more minerals than the number of elements is because minerals are not made up of a single element only. They are made of more than one elements and in some case a combination of elements .
There are 92 naturally occurring elements on Earth. Elements beyond uranium (atomic number 92) are not found naturally, except for trace amounts of some transuranic elements like neptunium and plutonium that are formed in nuclear reactions or decay processes.
No, not all naturally-occurring elements are essential to living organisms. While some elements are required for life (such as carbon, oxygen, hydrogen, and nitrogen), others like arsenic and mercury are toxic and harmful to living organisms. Each element has different roles and impacts in biological systems.
The least common elements are the synthetic elements, like ununoctium, since they exist for a very small fraction of a second, however, some naturally occurring elements like lawrencium have only a life of 3 hours, so it is a very rare element
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.
