There is a rather good article at http://www.ece.mtu.edu/faculty/wfp/articles/hp_9_twocol.pdf which I hope will be helpful to you.
The sources of polarizability include the electronic cloud of an atom or molecule, which can be distorted by an external electric field, causing polarization. This distortion leads to the formation of temporary dipoles, inducing a dipole moment in the atom or molecule. Additionally, the structure and symmetry of the atom or molecule also play a role in determining its polarizability.
Electronic polarization of a hydrogen atom refers to the distortion of the electron cloud around the nucleus in response to an external electric field. This distortion results in a separation of charge within the atom, causing a dipole moment. The magnitude of this polarization depends on the strength of the external electric field and the polarizability of the atom.
Polarizability is a measure of how easily the electron cloud of an atom or molecule can be distorted by an external electric field. It can be experimentally determined by measuring the relative change in polarizability when subjected to an external electric field. Quantum mechanical calculations can also be used to predict polarizability based on the electronic structure of the system.
It is a measure of how easily an electron cloud is distorted by an electric field. Electron cloud will belong to atom, molecule or Ion. It is the quantitative measurement of the extent to which the electronic cloud can be polarized
The smallest atom is hydrogen.
There are at least 36.
the atom with the least mass is the hydrogen atom
Polarizability
There is one atom of hydrogen in a hydrogen molecule.
A hydrogen ion can change into an atom by gaining an electron. When a hydrogen ion, which is essentially a hydrogen atom that has lost its electron, gains an electron back, it will become a neutral hydrogen atom.
There is one atom in a hydrogen atom
yes the smallest atom is hydrogen
