specifically refers to the removal of electrons, such that a positively charged cation of +1 charge or greater is formed. The first electron removed is the most loosely bound valence electron. Ionization energy has trends in the periodic table and strongly depends on the atom's...
Overview Initialize Atomic Ionization Energies and Periodic Trends Appendix Overview Very often, chemical reactivity can be thought of in terms of ionization energies. For example, the lower an atom's ionization energy, the higher its reactivity. For an atom X, its ionization energy, IE, can...
The barrier heights decrease on going from left to right in the periodic table, and increasing ionization energy (of X and XH) is correlated with decreasing barrier. The observed trends are explained in terms of substrates with stronger electrostatic character giving rise to lower energetic barriers...

Ion size trends in periods. Going from left to right there is a decrease in size of positive ions. Starting with group 5, there is sharp increase followed by a decrease in the size of the anion as you move from left to right.
What is the effect on the size of the atom when going from left to right in the periodic table? Explain the trend of ionization energy as you move down the column of the Group 16 elements. Describe the major trends in metallic character observed in the periodic...
