process of removing an electron from a stable nucleus

The attractive force between the nucleus and the electron increases with the increase in nuclear charge making it more difficult to remove an electron. The ionization energy thus increases with the increase in the nuclear charg..

The process of electrorefining of metals involves the following steps: The electrolyte is usually an aqueous solution of the salt of the metal with some corresponding acid, if necessary. A thick block of impure metal is made the anode. A thin rod/sheet of pure metal is made the c..

When the nuclear charge is high there is greater attraction for the incoming electron. Therefore electron affinity increases as the nuclear charge increases. With the increase in the size of the atom the electron affinity decreases because the distance between the..

.79 which is higher than that of iodine i.e., 3.28. Hence, chlorine accepts the electrons more easily than iodine. Electron affinity increases from left to right across the period because of increase in nuclear charge and decrease in atomic size. This causes the incoming el..

Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that has least energy is..

The 's' electrons are more penetrating (maximum probability of finding near the nucleus) towards the nucleus than the p electrons. The order of penetration power in a given shell is s > p > d > f If the penetration power of the electron is..

Alkali metals have the lowest ionization energy in each period. Within the group, as we go down, the ionization energies of alkali metals decrease due to their atomic size being the largest in their respective periods. In large atoms the valence electrons are loosely held by the nu..

. A positron has same mass as an electron but with the opposite charge. So, when an electron and positron are brought together they annihilate and their mass gets converted into energy. The reverse of this process is also possible. It is called as pair production. A ph..

The electronic configuration of nitrogen (1s 2 2s 2 2p 3 ) shows that it possesses exactly half-filled 'p' orbitals as its outershell configurations. Since, half-filled orbitals are extraordinarily stable, it is more difficult to remove an electron from this..

This process is the reverse of annihilation of matter. A photon of energy 1.02 MeV nearing a massive nucleus, under its intense electric field, splits up into a pair of particles - an electron and a positron. Thus, energy has been materialised by converting it into ma..
