As a chemistry expert, I am delighted to delve into the fascinating world of elements and their interactions. An ionic element is a term that might be a bit misleading, as elements themselves are not classified as ionic or covalent; rather, these terms describe the types of bonds that can form between atoms when they combine to form compounds. However, I understand that you are asking about ionic compounds and the elements involved in them.
Ionic compounds are formed when there is a transfer of electrons from one atom to another, resulting in the formation of ions. These ions are charged particles, with cations being positively charged and anions being negatively charged. The electrostatic attraction between these oppositely charged ions holds the compound together.
The formation of ionic compounds typically occurs between a metal and a non-metal. Metals tend to lose electrons to achieve a stable electron configuration, often resembling that of the nearest noble gas. This loss of electrons results in the formation of cations. On the other hand, non-metals tend to gain electrons to fill their outermost shell and achieve stability, resulting in the formation of anions.
The driving force behind the formation of ionic bonds is the difference in electronegativity between the atoms involved. Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond. When the electronegativity difference is significant (typically greater than 1.7 on the Pauling scale), the bond formed is considered ionic.
Let's consider an example to illustrate this concept. Sodium chloride (NaCl), common table salt, is an ionic compound. Sodium (Na), a metal, has an electronegativity of 0.93, while chlorine (Cl), a non-metal, has an electronegativity of 3.16. The difference in electronegativity is quite large, leading to the transfer of an electron from sodium to chlorine. Sodium loses an electron to become a positively charged ion (Na+), and chlorine gains an electron to become a negatively charged ion (Cl-). The resulting ionic compound, NaCl, is held together by the strong electrostatic forces between the Na+ and Cl- ions.
Ionic compounds have distinct properties that set them apart from covalent compounds. They are generally crystalline solids at room temperature, have high melting and boiling points, and are soluble in water. When dissolved in water, they form solutions that can conduct electricity due to the presence of mobile ions.
It is important to note that while the distinction between ionic and covalent bonding is clear in many cases, there is a spectrum of bond types, and some compounds exhibit characteristics of both. These are known as polar covalent bonds, where the sharing of electrons is unequal, leading to a partial positive and partial negative charge on the atoms involved.
In summary, while there is no such thing as an "ionic element," the concept of ionic bonding is crucial in understanding the behavior and properties of many elements when they form compounds, particularly those involving metals and non-metals.

Compounds containing two elements (so called binary compounds) can either have ionic or covalent bonding. If a compound is made from a metal and a non-metal, its bonding will be ionic. If a compound is made from two non-metals, its bonding will be covalent.
