Ionization energy monatomic

All the elements have stable electronic configurations (Is or ns np ) and, under normal circumstances are colourless, odourless and tasteless monatomic gases. The non-polar, spherical nature of the atoms which this implies, leads to physical properties which vary regularly with atomic number. The only interatomic interactions are weak van der Waals forces. These increase in magnitude as the polarizabilities of the atoms increase and the ionization energies decrease, the effect of both factors therefore being to increase the interactions as the sizes of the atoms increase. This is shown most directly by the enthalpy of vaporization, which is a measure of the energy required to overcome the... 

Nonmetallic elements do not typically form monatomic cations, because their ionization energies are too high. The nature of bonds between... 

The energies of ionization of monatomic nitrogen to various stages are taken from the following works Hopfield4 and Compton and Boyce,1 first step Bowen2 and Fowler and Freeman,1 second step Bowen,2 Millikan and Bowen,3 4 and Freeman,1 third step Edlen,1 fourth step Edlen and Ericson,5 fifth step. The values for the sixth and seventh steps are taken from the calculations of Laporte and Young.1... 

From a theoretical point of view30 one expects deviations from Eq. (1) to occur for reasons already present in monatomic entities. The optical transition a —> b does not depend only upon the difference between the ionization energies but also effects of interelectronic repulsion to be described to the first approximation by...

Draw the partial (valence-level) orbital diagram and write the electron configuration of the atom and monatomic ion of the element with the following ionization energies (in kJ/mol) ... 

The metallic elements generally have low ionization energies and low electronegativities compared with the nonmetalUc elements. As a result, the metals tend to lose their valence electrons to form cations (Na, Ca, Al " ) in compounds or in aqueous solution. Nonmetals, on the other hand, form monatomic anions (O, Cl ) and oxoanions (N03, S04 ).
