What is a bond in which one element loses an electron and anohther gains an electron?

A bond in which one element loses an electron and another gains an electron is called an ionic bond. This type of bond typically occurs between metals and nonmetals, where the metal donates one or more electrons to achieve a stable electron configuration, while the nonmetal accepts those electrons. The result is the formation of positively charged cations and negatively charged anions, which are held together by the electrostatic forces of attraction. This interaction leads to the creation of ionic compounds, such as sodium chloride (table salt).
