How many neutrons protons and electrons does fermium have?
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
What is the atomic mass of fermium?
The most stable fermium isotope, 257Fe, has an atomic mass of 257, 095 105.
What is the nucleus of fermium?
The nucleus of fermium contain 100 protons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 100
What is the difference between mass number atomic mass and atomic number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atomic mass number of krypton?
83.98 amu is the Atomic Mass, 36 is the atomic number.
