Francium has an atomic covalent radius of 260 pm, is radioactive and very unstable.
Iron.
No. In fact the largest stable nucleus of any atom in it's non isotope form is Lead at 82 protons
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.
A stable atom of hydrogen (H)
Uranium atom is the heaviest.
It is called proton.It is found in the nucleus of each atom, along with neutrons, but is also stable by itself and has a second identity as the hydrogen ion, H+.
30 neutrons in the most stable isotope of iron (Fe-56).
No. In fact the largest stable nucleus of any atom in it's non isotope form is Lead at 82 protons
Yes. Sodium has 12 neutrons whereas iron has 30 neutrons for their most stable isotpe.
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...

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

True
20 for the stable atom
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.
A stable atom of hydrogen (H)
The amount of protons in the nucleus of an iron atom is greater than in that of an aluminum atom.
The atoms having 2 protons only in nucleus is not stable but 2 protons with 2 neutron in Helium nucleus are very stable.
