The periodic table is arranged by various patterns. Is there a pattern with regard to ionic charge? In three to five sentences, explain your reasoning and provide specific examples.

Yes, there is a pattern with regard to ionic charge in the periodic table. The ionic charge of an element is typically determined by the number of valence electrons it has. Elements in the same group or column of the periodic table tend to have the same number of valence electrons and therefore similar ionic charges. For example, all elements in Group 1 (alkali metals) have one valence electron and form ions with a +1 charge. Similarly, elements in Group 17 (halogens) have seven valence electrons and tend to form ions with a -1 charge.
