There are two main variables that determine the distance of electrons from the nucleus. This is how many electrons are present, with less being farther away in the same energy level. The second is the energy level they are located in, with distance increasing with level.
The distance is proportional to the time shell layers within the quantum Higs field .Every shell layer has a proportional power which is equal to but not the same as the strong force .The quanta within the shell fields are of spin 1/1 t - 1/n t ie all possible states at all possible times in all dimensions .Einstein called this phenomenon the cosmological constant which he later claimed was his biggest mistake but was really his greatest vision now the LHC has proved the so called God particle has Mass in some dimensions and no mass in others .
The radius of an atom is a fuzzy concept because the exact position of an electron is always indeterminate due to the uncertainty principle and must be expressed in probabilities rather than exact positions. Although the radius of an atom increases a bit as you go down the Periodic Table to heavier periods, decreases a bit as you go across the table to heavier atoms within each period, and increases quite a bit when sharing a valence electron with another nucleus, the radius is roughly on the order of one Angstrom, and varies from 1/3 Angstrom to 3 Angstrom. Note that the radius of heavy atoms with more protons and electrons is not necessarily larger than the radius of lighter atoms with fewer protons and electrons: one Angstrom is still the proximate size.
The electron energy is a quaternion energy with a real and vector energy:
E = Er + Ev = -e^2zc/4pi r + mcV = c(Pr + Pv)
the real or potential energy is Er = -e^2zc/4 pi r and the vector energy is Ev = mcV where m is the mass of electron and V is the velocity.
The Conservation of the Electrical Energy gives the Fine Structure Constant:
e^2z/2nh = cos(V) = (7.2E-3)/n
The Redshift 'z' = cos(V) = Alpha, the Fine Structure Constant.
The distance varies to close to zero for s electrons in inner shells up to 200-300 pm in neutral atoms of heavier elements.
The energy of the electron resists, to some extent, the attraction of the nucleus. This amount of energy determines the distance of the location of the electron.
the force of attraction between then nucleus and the valence electrons is less than that between the nucleus and the core electrons
The charge on the nucleus.The distance of the electron from the nucleus.The number of electrons between the outer electrons and the nucleus.
Is called a shell. The first shell around the nucleus can hold a maximum of two electrons. While the second shell can hold a maximum of eight electrons.
The atomic radii is an estimation of the radius of an atom. The value of the atomic radii is based off an approximation of the distance from the atom's nucleus to the edge of the atom's electron cloud.
The K shell is closest to the nucleus, and is the smallest shell, so when electrons are in that shell they are close to each other, and therefore also have a strong repulsion toward each other (since the electrostatic force varies inversely according to the square of the distance between two charged objects). The attractive force between the positive nucleus and the negative electrons is enough to hold two electrons in the K shell, but if a third electron were to enter that shell, the repulsive force between the three negatively charged electrons would be greater than the attraction that the electrons would have for the nucleus, and therefore one of the electons would be forced out of the shell.
As alkali metals increase in size, the distance of the outermost electrons from the nucleus increases. The attraction between the electrons and the nucleus is electrostatic, and it is a fundamental property of electrostatic attractions that the attraction decreases with increasing distance between the attracting charges. Another way of describing this is that the attractive force is partially "screened" by the inner electrons between the outermost electrons and the nucleus.
No, electrons are around nucleus but at a great distance.
The Bohr radius, is the estimated distance between protons in the nucleus and electrons - but electrons aren't solid, stationary particles... The simple answer would be about one-twentieth of a nanometre. But this would only be reasonable if the electron were a solid particle.
Distance.
all electrons are alike
Protons are contained within the nucleus, electrons surround the nucleus at a considerable distance (atomically speaking)
valence electrons
shell
the force of attraction between then nucleus and the valence electrons is less than that between the nucleus and the core electrons
Protons and neutrons make up the nucleus in an atom, the electrons are in shells or orbits around that nucleus at quite a distance (relatively to the nucleus diameter)

A: If a nucleus is a point like a flag pole then the electrons are orbiting this nucleus at a very big distance like football filed distance and they have a charge too
