Fermium exist only in specialized and very rare laboratories.
Fermium has 100 protons and electrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of fermium is 100; but fermium has 17 isotopes, each with a different number of neutrons. For the most stable isotope of fermium, 257Fm: protons-100 electrons-100 neutrons-157 atomic mass per unit (AMU)-257
The atomic number (not isotope number) of fermium is 100.
Only isotopes Fr-221 and Fr-223 are natural.
Fermium is an artificial chemical element, metal, actinoid, radioactive, atomic number 100.
Fermium and einsteinium were discovered in the debris from the thermonuclear test, Enawetak -1952. And also fermium has the atomic number 100.
Fermium is an artificial chemical element, metal, toxic, radioactive, atomic number 100, etc.
Fermium is an artificial element, solid, metal, radioactive, actinoid, atomic number 100.
The atoms of fermium have 100 protons each.
Fermium is a synthetic element with atomic number 100. It does not occur in nature. It is a highly radioactive transuranic element.

Fermium. To find this type of information, you look at a periodic table. You will find a really useful one here: www.rsc.org/periodic-table/?gclid=CjwKEAjw2MOhBRCq-Nr87_j-lDASJAAl4FNhssVbsyCT_UjwmmrpVjUngib6tHybHy88YrC1gH_1shoCZDzw_wcB
Fermium is a metal, solid, member of the actinoids family, period 7, artificial, radioactive, atomic number 100, etc.
