What are the 9 naturally occuring elements and 21 artificially created elements in the periodic table?

Question

By elements I mean Hydrogen Silicon Boron Neon Sulfur etc.

By naturally occuring, I meant to say naturally occuring on earth. Sorry if I got everyone confused.

Answer 1

most elements i think are naturally occuring. most of the ones that are artificial are the ones with really high atomic numbers. those are so unstable that scientists are only able to have them exist for less than a second before they break apart again D:

Answer 2

All elements up through 94 occur naturally (although neptunium and plutonium are extremely rare since they are made from uranium by natural processes), except for two: technetium and promethium, which have no stable isotopes. Thus there are 92 different elements found in nature. Elements 93 through 115 appear to have been created artificially, with less certainty in the higher numbers; there is also a report of having created element 118.

Answer 3

The last time I looked at the periodic table (and I look at it many times each day) I saw a few more than 9 natural elements. Chemistry books state that everything up through 92 - Uranium - is naturally occurring. Of course, they are not all found in the same percentage on Earth. Perhaps you mistyped your question or had some misleading information.

Answer 4

I was always taught that all elements up to uranium (92 as I recall) were naturally occurring. Where do you come up with only 9??? It is true that Francium is extremely rare to non-existent. And that plutonium which is artificially created has been found in nature, albeit in extremely low concentrations. So, I don't understand your question.

Answer 5

I bet the "naturally occurring," part means elements that are found in nature in pure, elemental form, instead of compounds. I still think there's more than 9, starting with all the noble gases, O, N, H, gold, silver, platinum, copper.... there's gotta be more than 9 still.

Answer 6

What exactly are you asking for? Do you want to know which elements are present in nature in their elemental form?
I believe magnesium (Mg), calcium (Ca), gold (Au), silver (Ag), platinum (Pt), carbon (C), iron (Fe), and the noble gases (Group VIII, or 18 depending on how your table lists the groups) all exist in elemental form. Several naturally occuring radioactive isotopes for different elements also exist, such as for C, phosphorus (P), iodine (I), sulfur (S). Elements like oxygen (O), and the Halogens (Group VIIA or 17) exist in nature as their dimers eg O2, F2, Cl2, etc. Ozone is three oxygens (O3).

Synthetic elements (more than 21) are generally created as by-products/decay of radioactive elements. They are in abbreviated form Tc, Pm, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg, Uub, Uut, Uuq, Uup, Uuh, Uus, Uuo, Np, Pu, Am, Cm. Bk, Cf, Es, Fm, Md, No, Lr

Answer 7

only the bottom seperate part of periodic table is really artifical as the rest have been found naturally but maynot not in large quanties. Hyrdogen, helium, copper, gold, aluminum, silver, boron, neon, sodium, potassium, lithium, lead, zinc, chlorine, flouride, oxygen, iron, calcium, cesium, titanium, magnesium, beryllium are all some natural elements

Answer 8

i only know the artificially created elements:(look on the periodic table) number 61,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112

Answer 9

right both times
