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.(4 points)
Yes, there is a pattern with regard to ionic charge on the periodic table. The ionic charge of an element is determined by the gain or loss of electrons to achieve a completely filled outer electron shell. Elements in the same group on the periodic table tend to have the same number of valence electrons, which influences their ionic charge. For example, group 1 elements, such as lithium (Li), sodium (Na), and potassium (K), all have a single valence electron and tend to lose this electron to form a +1 ionic charge. Similarly, group 17 elements like fluorine (F), chlorine (Cl), and bromine (Br) tend to gain one electron to achieve a stable octet, resulting in a -1 ionic charge. Thus, the periodic table shows a pattern in ionic charge based on the number of valence electrons in each element.
