Consider the following very rough model of a beryllium atom. The nucleus has four protons and four neutrons confined to a small volume of radius 10^(-15)m . The two 1s electrons make a spherical charge cloud at an average distance of 1.3 xx 10^(-11) m from the nucleus, whereas the two 2s electrons make another spherical cloud at an average distance of 5.2 xx 10^(-11) m from the nucleus. Find the electric field at (a) a point just inside the 1 s cloud and (b) a point just inside the 2s cloud.

An electron is revolving in an orbit of radius 2Å with a speed of 4 xx 10^(5) m//s . The angular momentum of the electron is [M_(e) 9=xx10^(-31) kg] .

The size of an atomic nucleus is 10^(–14) m. Calculate uncertainty in momentum of an electron if it were to exist inside the nucleus.

The extent of localization of a particle is determined roughly by its de Broglie wave. If an electron is localized within the nucleus (of size about 10^(-14) m) of an atom, what is its energy? Compare this energy with the typical binding energies (of the order of a few MeV) in a nucleus and hence argue why electrons cannot reside in a nucleus.
