Because scientists just simply add a proton to an element, and they get the next element. For example, of you had one sodium atom (all sodium atoms have an atomic number of 11), and added a proton to it, you would get magnesium atom (all magnesium atoms have an atomic number of 12). So if scientists did this with element 99, they get element 100.

∙ 16y agoBecause all the elements with atomic number less than 100 have been discovered. There's one of each.

∙ 14y agobecause no element will have the same atomic number and we have discovered all of the elements with the atomic number under 100

How many elements are left to discover?
There are many more! Just like we always discover new planets, we are always discovering new elements, too.
What are all the elements that do not have isotopes?
There are many elements that have only one naturally occurring isotope. When you get to transuranic elements the elements all have no naturally occurring isotopes. But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
The millions of compounds that exist are made from approximatley how many elements?
The most common elements for a compound are the following:HydrogenOxygenCarbonNitrogenChlorineIodinePotassiumBromineCesiumFluorineRubidiumWhy you might ask?These are all the natural occurring Alkali Metals, Halogens, and Diatomics. Carbon and Hydrogen are needed for basic sugars, hydrocarbons, carbohydrates, and much more so I threw them in there.
About how many elements are in the periodic table of elements?
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.
What is the densest of the naturally occurring elements?
Osmium is slightly more dense than Iridium by a small fraction.
How many are there in the periodic table?
assuming you mean elements, there are 92 naturally occurring elements. 93+ are man made and the are still creating more.
How many elements are left to discover?

How many elements are in the elements table?
There are about 112 elements identified and for the time being 6 more proposed. 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. All elements after atomic number 92, are man made.
What is redioactive element?
A radioactive element is one that does not have a stable occurring isotope. Some of these elements include astatine, radon, technetium, promethium and so many more.
Are there no new elements to be discovered?
No. Uranium is the heaviest naturally occurring element. More elements can be prepared artificially. New isotopes of the element may be discovered.
What are all the elements that do not have isotopes?
There are many elements that have only one naturally occurring isotope. When you get to transuranic elements the elements all have no naturally occurring isotopes. But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
How can there be 2000 minerals when there are only 88 naturally occurring elements?
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 what?
You might be referring to the chemical elements. However, we are now aware that there are 96. For more information you might wish to consult the wikipedia page about chemical elements.
How deos the number of known compounds compare with the number of known elements?
There are at least five million distinct chemical compounds known. This compares to only 91 naturally occurring elements and about thirty more synthetic elements.
Is everything made out of dust or water?
No. There are 92 naturally occurring elements, and everything in our world is made out of one or more of these elements. Water, itself, is made by the combination of two gases, hydrogen and oxygen.
Are the group 8 elements intert?
The naturally-occurring group 8 elements (helium, neon, argon, and kyrpton) are not completely inert, but they are more nearly so than any other group.
Why are synthetic elements dangerous?
While there are some stable synthetic elements (eg technetium) and also naturally occurring elements which are radioactively unstable (eg radium), synthetic elements are more likely to be radioactively unstable. Their decay process produces radioactive emissions which are hazardous.
