Stable electron configurations are likely to contain

filled energy sub levels.

Explanation:

Stable electron configurations are likely to contain filled energy sub levels.

For each entity and ion, the electron configurations are special. The electron structure of an atom or ion shows us where electrons are clustered around an atom or ion's nucleus. There are seven levels of energy and four types of orbitals in which electrons are in an atom.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
