For each of the following atomic numbers, use the periodic table to write the formula (including the charge) for the simple ion that the element is most likely to form. $\begin{array}{llll}{\text { a. } 53} & {\text { c. } 55} & {\text { e. } 9} \\ {\text { b. } 38} & {\text { d. } 88} & {\text { f. } 13}\end{array}$

Key Concepts

Atomic Number

Atomic number represents the number of protons in the nucleus of an atom and uniquely identifies an element. It is the starting point for determining an element's position in the periodic table, which in turn gives clues about its chemical behavior and properties.

Periodic Table Structure

The periodic table arranges elements based on increasing atomic numbers as well as similarities in their electronic configuration and chemical properties. The table's organization into groups and periods provides valuable information about the valence electrons and potential charges that an element is likely to form.

Valence Electrons

Valence electrons are the electrons in the outermost shell of an atom and are primarily responsible for its chemical reactivity and bonding behavior. Knowing the number of valence electrons helps predict whether an element will gain or lose electrons to form ions and what charge these ions will carry.

Ion Formation and Charge

Ion formation occurs when an atom loses or gains electrons to achieve a more stable electron configuration, often that of a noble gas. The resulting ion carries a net charge, which is usually predictable based on the element's position in the periodic table and its valence electron count.

Metallic and Nonmetallic Character

Elements with metallic characteristics tend to lose electrons, forming positively charged ions (cations), while nonmetals are more likely to gain electrons to form negatively charged ions (anions). This distinction is crucial for predicting the type of simple ion an element is most likely to form.
