Manganese has only one isotope that occurs in nature. Its atomic mass is approximately 54.940 amu.
Some do, some don't. Scandium and manganese, for example, do not, copper has only two isotopes.
Manganese is a metal so it is monatomic, meaning 1 atom.
10 isotopes 10 isotopes
Californium has 20 isotopes and 1 isomer.
Natural gallium has 2 stable isotopes
Some do, some don't. Scandium and manganese, for example, do not, copper has only two isotopes.
Many atoms have many different isotopes, and each isotope has a different number of neutrons. Mn only has 1 stable isotope, which is 55 atomic mass. It is atomic number 25 and thus has 30 neutrons.
Nearly 100% of manganese found in nature is 55Mn, which is not radioactive. Trace quantities of 53Mn, which is radioactive, are found in nature, but they are insignificant. Like all elements, synthetic radioactive isotopes of manganese exist.
Manganese is an element
The element manganese has 25 protons in its nucleus. You'll recall that the number of protons in an atom gives it its chemical identity, and only that. It will also have 25 electrons when the atom is in the neutral state. (Manganese normally "loans out" electrons in chemical reactions.) There are 30 neutrons in the only stable isotope of manganese, but there are a number of different isotopes of this transition metal. They've been synthesized, of course, and the number of neutrons ranges from 19 through 44. A link can be found below.
Mendelevium has 15 isotopes.
Germanium has 9 isotopes.
No, there are many stable isotopes.
There are 37 isotopes of Hafnium.
Manganese is a metal so it is monatomic, meaning 1 atom.
13 electrons are in the third orbit of Manganese.
