Webb31 okt. 2015 · P b is the element that is in the lowest period at 6 (and lowest group at 14) in the periodic table; it's the smallest ionization energy. The period above (5) has two of the elements: Sn and Te. Well, since ionization energy increases across a period, Sn will have a smaller ionization energy than Te. P b,Sn,T e WebbThe first ionization energy is quantitatively expressed as X(g) + energy X + (g) + e −. where X is any atom or molecule, X + is the resultant ion when the original atom was stripped of a single electron, and e − is the removed electron. Ionization energy is positive for neutral atoms, meaning that the ionization is an endothermic process.

Worried about … bonita card roomWebbIn general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. This pulls the electron cloud closer to the nucleus, strengthening the nuclear attraction to the outer-most electron, and is more difficult to remove (requires more energy). godaddy for business email
