I suppose that a relation doesn't exist.
You can identify an element at an atomic level by the amount of protons, electrons and neutrons are in one of it's atoms. To do this you would need an electron microscope. You can also test for things like electrical conductivity and magnetism.
The atomic number and number of protons are always the same in a normal element.
Fluorine has a stronger attraction to electrons than any other element, so when it bonds to another element that element is going to either donate electrons to the fluorine, or share electrons with fluorine getting the disproportionate share.
Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.
The element is helium, with symbol He.

The electrical conductivity is not know, Thermal conductivity is 0.00565 W/(m·K)
Modern models suggest that there is not a fixed relationship between the various electrons in a given shell. The electrons conform to a probability model in their positioning. [And this may go a little way to explaining radioactivity?]
electrons
yeah of course.. as indeed the presense of electrons is a chemical property but the necessary thing for conductance is the orientation of electrons that depends upon the nature of element that is the physical property of element..

Conductivity test, Scratch test, Density test, Properties and Malleability ... :)
From Wikipedia: In chemistry, a metal (Greek: Metallo, Μέταλλο) is an element, compound, or alloy characterized by high electrical conductivity. In a metal, atoms readily lose electrons to form positive ions (cations); those ions are surrounded by delocalized electrons, which are responsible for the conductivity. The thus produced solid is held by electrostatic interactions between the ions and the electron cloud, which are called metallic bonds. From me:If an element shows these characteristics, it is a metal. Calcium shows these characteristics. Therefore, Calcium is a metal.
it depends which one.
They have the same number of valence electrons (electrons in their outermost shell). They do not have the same number of shells however.
The atomic number and number of protons are always the same in a normal element.
