Yes. Sodium has 12 neutrons whereas iron has 30 neutrons for their most stable isotpe.


Do protons in a very large nucleus have a greater chance of flying apart?

Sort of... The general tendency is for a larger atom to be less stable. Above a certain point (after lead) no stable atoms are known to exist.Sort of...

Does an atom become most stable when trying to fill its nucleus?

It becomes most stable when its nucleus is filled, not when it is filling it.


How can you predict whether an isotope nucleus is likely to be stable?

You can not predict whether an isotope nucleus is likely to be stable. There is a lack of electrons in the nucleus creating a chemical change in the atom becoming stable.

How do you account for the number of protons?

The atomic number of an element accounts for the number of protons in the nucleus of the atom of that element. For example: * Hydrogen atomic number is one. The nucleus of its atom has one proton. * Oxygen atomic number is 8. The nucleus of its atom has 8 protons. * Iron atomic number is 26. The nucleus of its atom has 26 protons. * Lead atomic number is 82. The nucleus of its atom has 82 protons. * Uranium atomic number is 92. The nucleus of its atom has 92 protons.

If an atom has two protons would it be stable?

The atoms having 2 protons only in nucleus is not stable but 2 protons with 2 neutron in Helium nucleus are very stable.
