Penetration power of electrons means the power of orbitals to attract electrons.
More the penetration power of electrons , More will be the ionization Enthalpy (Amount of energy required to remove one electron)
Perhaps having to do with impulse (2nd derivative) and brissance, or the converse thereof?
Penetration power is the ability of radiation to pass through matter
is the ability of entering to the substance
Gamma, i.e. photon emitted from the nucleus, has the highest penetrating power.
If you are asking about which radiation is the most penetrating, gamma rays are the "strongest" in that regard.Gamma rays are electromagnetic radiation of the highest possible energy (frequency). It has a higher frequency (shorter wavelength) than even X-rays. It has the greatest ability to penetrate materials. A gamma ray can go through a hundred people with ease.It takes a very large mass to be effective in stopping gamma radiation. Any material can be used as shielding but, in general, the more mass, the better. It takes a lot more water than lead to stop gamma rays because water is much less dense than lead, but water is cheaper. Stone, concrete, or soil is very cost effective.Any of these radiation may be emitted from the nucleus of an atom during radioactive decay (depending on the type of decay). They all ionize material as it slows them down. Both alpha and beta radiation are particulate radiation, as they are composed of particles.Alpha particles are helium-4 nuclei, composed of two protons and two neutrons. These don't travel very far in air, and a sheet of paper will stop them.A Beta particle is a high energy electron or positron. These have a modest ability to penetrate, but a sheet of aluminum foil will stop them.
Alpha particles are the least penetrating form of radiation. However, that does not mean they are the least dangerous. Even though they can be stopped with only an inch or so of air, or even by our skin, if they are ingested and come into contact with sensitive body tissues, they can be dangerous, because they have the highest charge and the highest mass.
A beta particle has an electric charge of -1 because beta particles are both lightweight and fast moving, they have a greater penetrating power than alpha particles.
paticles of water can be seperated by penetrating heat into the cells
Low ionising power results from great penetrating power.
Beta particles have a very low penetrating power; an aluminium foil of 3-4 mm is a sufficient shielding.

Gamma, i.e. photon emitted from the nucleus, has the highest penetrating power.
Alpha being so massive penetrates with less power. Beta lighter yet massive has less penetrating power. But gamma being just a radiation/non-massive photon penetrates with highest power
ultra voilet rays are characterized with high penetrating power ============================= The EM radiation with the highest penetrating power would be the flavor with the highest frequency/shortest wavelength. Those are the waves we call "gamma rays". A moment's thought will remind you that X-rays are more penetrating than ultraviolet rays are ... otherwise we'd be getting dental ultraviolets instead of dental X-rays.
Alpha particles are positively charged. They have low penetrating power but high ionizing power.
The most penetrating power is for beta particles compared to those given here.
