WebbTwo species (atoms, molecules or ions) are isoelectronic if they have exactly the same number and arrangement of electrons (including the distinction between bonding pairs and lone pairs). The hydroxonium ion, H3O+ Oxygen is in group 6 - so has 6 outer electrons. Add 1 for each hydrogen, giving 9. Take one off for the +1 ion, leaving 8. Webbessentially constant over the complete sorption range. A&, changes very little once most of the pore space is filled, as the environment of the sorbed molecules remains nearly constant. Consequently, AC, is almost invarient from about 5 to 6.5 molecules sorbed per unit cell (Figure 4). This could clearly lead to sorption hysteresis being observed in …
