In the periodic table, the charges of ions formed by elements across a row (or period) generally follow a predictable pattern based on their position. As you move from left to right across a period, elements tend to lose electrons and form positive ions (cations) or gain electrons to form negative ions (anions). For example, in the second period, lithium (Li) and sodium (Na) in Group 1 typically form +1 cations, while fluorine (F) and oxygen (O) in Group 17 typically form -1 and -2 anions, respectively. This trend occurs because elements on the left side of the table have fewer valence electrons and tend to lose them, while elements on the right side have more valence electrons and are more likely to gain electrons to achieve a full outer shell.
