Why does nuclear size vary linearly with atomic mass number? Nucleus contains nucleons viz; protons and neutrons. Nucleus is not just pile of balls (neutrons and protons) as is generally depicted in many cases. And we don't know much about nucleus. Obviously linear variation of size with atomic mass number is experimented fact. What are theoretical explanations for this?

The volume of a nucleus varies approximately as the atomic number A, and for that (large) subset of nuclei that are spherical or ellipsiodal, the median axis varies approximately as A 1 / 3 .
These results can be had from data and also arrived at as results in shell models.

Earth has a magnetic dipole moment of
8.0 × 10 22 J / T
(a) What current would have to be produced in a single turn of wire extending around Earth at its geomagnetic equator if we wished to set up such a dipole? Could such an arrangement be used to cancel out Earth’s magnetism
(b) at points in space well above Earth’s surface or
(c) on Earth’s surface?

To state the title question perhaps more precisely:
What is the largest photon energy E γ and the corresponding mass number A and atomic number Z of a suitable nucleus Z A X (presumably in a ground state) such that the hypothetical reaction
Z A X + γ ( Z z ) ( A a ) Y + whatever remains (with combined charge + z )
is "kinematically" forbidden for any values 1 a < A and Z z Z + a A,while conforming to the standard model?

Let us think of a covalent bond between two atoms A and B. Since in covalent bond,sharing of electrons take place, valence eletrons of one atom behave as the electrons of the other atom. So since A gets B's share of electrons, it's electron number has increased more than before. If the atomic number of A is x,now proton number of A is x and electron number is x + something,so number of electron is more than proton and as such w.r.t A, A develops negative charge. Similarly B develops negative charge. But we know there is no charge formed in covalent bond. So where is my misconception?

What is the relation between the atomic number of material, density and radiation detection for semiconductor radiation detectors?
Lead is considered to be the one of the preferred materials to shield against radiation due to its high atomic number and density. Can the atomic number and density be applied to materials for radiation detectors such as semiconductor radiation detectors as well?
