how may elements occur naturally in nature
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
There are 92 naturally occurring elements on Earth.
Uranium, element number 92, is the largest naturally occurring element. However, francium, 87, and astatine, 85, along with any element with an atomic number larger than 92 are not found in nature. They are produced in the laboratory. If they do occur naturally they are in exceedingly small quantities. So to answer your question "How many elements can't be found in nature?" about 16 or a few more.
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.
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.
There are 94 naturally occurring elements on the periodic table. These elements range from hydrogen (1) to uranium (92), with elements 93 (neptunium) and 94 (plutonium) also occurring in nature, though less commonly.
There are currently 118 elements, ranging from #1 Hydrogen to #118 Ununoctium. Many of the transuranium elements (#93-#118) are synthetic, meaning that the only place they have been found is in a laboratory, thus do not exist in nature. Technetium (#43) and Promethium (#61) are also synthetic.
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
There are 90 elements that exist naturally.
92 elements occur naturally on the periodic table.
Clarification needed: How many are found un-bound (pure) in nature? For example: pure gold nuggets, atmospheric nitrogen, etc. Or how many are naturally occurring on Earth (even if they're in compounds and not pure) vs. how many are created only by humans in a lab?
