The threshold atomic number below which fusion may occur is around 5-6. This is because atomic nuclei with lower atomic numbers have less electrostatic repulsion, allowing them to overcome the Coulomb barrier and fuse together.

The average Atomic Mass
The atomic number is equivalent to the number of protons in the nucleus. See the Periodic Table of elements at the link below.
The atomic number is the whole number indicating the number of protons. It is usually directly above or below the element symbol.
The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.

The number of neutrons= Atomic mass of an isotope-Atomic number of the elemnent For the atomic weights of elements (not mass) please read the IUPAC report at the link below.
Below uranium in the periodic table are all the elements with atomic numbers between 1 and 91.The atomic number of uranium is 92.
The element below sodium with atomic number 11 is lithium. Lithium is a metal in the same alkali metal family as sodium.
Curium has 96 protons. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; for the isotopic masses of curium read at the link below.
