Francium has an atomic covalent radius of 260 pm, is radioactive and very unstable.
No. In fact the largest stable nucleus of any atom in it's non isotope form is Lead at 82 protons
A stable atom of hydrogen (H)
A stable nucleon is a particle found in the nucleus of an atom, either a proton or a neutron, that is not subject to radioactive decay. These particles are essential for the stability of the nucleus and play a crucial role in determining the properties of the atom.
You can predict whether an isotope nucleus is likely to be stable by considering the ratio of protons to neutrons in the nucleus. Nuclei with a more balanced ratio of protons to neutrons tend to be more stable. Additionally, nuclei with magic numbers of protons or neutrons are also more likely to be stable.
The number of neutrons in an atom of a certain element varies from one isotope of that element to another. Iron has stable isotopes Fe-54, Fe-56, Fe-57 and Fe-58 Fe-54 has 28 neutrons, Fe-56 has 30 neutrons, Fe-57 has 31 neutrons and Fe-58 has 32 neutrons.
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.
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 amount of protons in the nucleus of an iron atom is greater than in that of an aluminum 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 distance of the electron cloud from the nucleus affects the atom's stability. When the electron cloud is closer to the nucleus, the atom is more stable. This is because the positively charged nucleus and negatively charged electrons are closer together, creating a stronger attraction. Conversely, if the electron cloud is further from the nucleus, the atom is less stable as the attraction between the nucleus and electrons is weaker.
The atoms having 2 protons only in nucleus is not stable but 2 protons with 2 neutron in Helium nucleus are very stable.
