I think you mean its atomic number, which is the number of protons in the nucleus
Electrons only.
I assume it's an incorrect spelling of "nuclear charge".
The term is nuclear fusion, where light elements (usually hydrogen) fuse to form heavier elements.
Nickel and iron
A nuclear electric quadrupole moment describes the effective shape of the ellipsoid of nuclear charge distribution. The quadrupole moment depends upon the size and charge of the nucleus.
Nuclear chemistry is the chemistry involved in nuclear processes; in a large sense may be considered also the chemistry of radioactive elements. Sometimes radiation chemistry (radiochemistry) is considered a chapter of nuclear chemistry.
Examples: - chemistry of water in nuclear reactors - separation of new artificial elements - radiochemical polymerization
Nuclear chemistry study nuclear materials and elements, isotopes, chemical processes involved in nuclear energy, some radioactivity applications, etc.
Traditional chemistry deals mainly with the interaction of elements, compounds, and energy. Nuclear chemistry studies the nucleus of atoms, and how it can split, decompose, and interact with energy.
Unstable chemical elements are disintegrated by radioactive decay.
The one difference that nuclear chemistry has from the other branches is its study of the nucleus (core) of the atom. Nuclear chemistry will deal with how the nucleus can split, absorb and release energy as radiation, and decompose to form different elements.
Seaborgium is important for the nuclear physics and the chemistry of artificial elements.
Nuclear chemistry is a branch of chemistry related to chemical processes involved in nuclear reactions.

Nuclear chemistry deals with the chemical reactions involving radioactive elements. Gamma radiation is due to the electromagnetic force, beta radiation is due to the weak nuclear force, and alpha radiation is due to the residual strong force (which you might call the strong nuclear force). So... if you didn't have the nuclear force, you wouldn't have alpha radiation.
The object of nuclear chemistry is the study of radioactive materials, nuclear wastes, chemical reactions in a nuclear reactor etc.
The elements are barium and radium - atomic radius 215 pm.
