True
30 neutrons in the most stable isotope of iron (Fe-56).
Yes. Sodium has 12 neutrons whereas iron has 30 neutrons for their most stable isotpe.
Francium has an atomic covalent radius of 260 pm, is radioactive and very unstable.
The most stable atom in the periodic table is helium.
The most stable atom is helium because it has a full outer electron shell, which makes it less likely to react with other atoms.
No. In fact the largest stable nucleus of any atom in it's non isotope form is Lead at 82 protons
It becomes most stable when its nucleus is filled, not when it is filling it.
The most stable state of an atom is called the ground state. This is when the electrons occupy the lowest energy levels available to them.
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
An iron atom is the smallest iron particle that still has the properties of iron.
less stable
Smallest is Hydrogen (H) Biggest is Iron (Fe) Fundamentally anything smaller than Iron will fuse together (and release energy) to make Iron and anything Larger than Iron will fission apart (and release energy) to make Iron. Thus simple hydrogen (made in the Big Bang) and Iron are the two stable atoms.
