Additionally, when using noble gas ion beams there is a "'high probability of neutralization on impact "'( which has strong angular dependence ) due to the strong desire of these ions to be in a neutral, closed shell state.

There is also an empty 3d level, but it is at considerably higher energy than 3s and 3p ( unlike in the hydrogen atom ), so that 3s 2 & thinsp; 3p 6 is still considered a closed shell for chemical purposes.
33.
An alkaline earth metal of Group 2 ( e . g ., magnesium ) is somewhat less reactive, because each atom must lose two valence electrons to form a positive ion with a closed shell ( e . g ., Mg 2 + ).
34.
M�bius aromaticity occurs when a cyclic system of molecular orbitals, formed from p ? atomic orbitals and populated in a closed shell by 4 " n " ( " n " is an integer ) electrons, is given a single half-twist to form a M�bius strip.

The pullout from Royal / Dutch Shell's oil pipeline pumping stations at Ogbotobo, Opukushi, Tumo and Benisede raises the number of closed Shell facilities to 14, cutting production by 320, 000 barrels of crude oil a day, a spokesman for Shell's Nigerian subsidiary said, speaking on condition of anonymity.
36.
On June 22 a fire closed Shell Chemical Co .'s Deer Park, Texas, refinery, forcing Shell to stop production of about 5, 000 bbl / day of MTBE . The company wouldn't comment on trader speculation that the MTBE plant would remain closed until at least the end of August.

For example, the total spin magnetic moment ( sometimes referred to as the " effective magnetic moment " when the orbital moment contribution to the total magnetic moment is neglected ) of a transition metal ion with a single d shell electron outside of closed shells ( e . g.
38.
Such nuclei tend to fission with the formation of isotopes close to the closed shells Z = 20 / N = 20 ( 40 Ca ), Z = 50 / N = 82 ( 132 Sn ) or Z = 82 / N = 126 ( 208 Pb / 209 Bi ).
39.
The closest shell to the nucleus is called the " shell " ( also called " K shell " ), followed by the " shell " ( or " L shell " ), then the " shell " ( or " M shell " ), and so on farther and farther from the nucleus.
40.
I could imagine the nature of a " photon " as being a quantity of force, bound into the form of potential energy, imposing that force on the " body " of an electron and thus'forcing'it down into a tighter, closer shell within the atom, only to'quiver'for a time before'releasing'or re-binding that extra force into another'photon'or potential energy and returning to it's original shell.
