I, too, prefer metaloids, but another word is amphoteres (meaning they are amphoteric).
Yes, you are correct. Elements that have properties of both metals and non-metals are called metalloids, not families. Metalloids are a group of elements found on the periodic table that have characteristics of both metals and non-metals. They exhibit properties such as being semi-conductors of electricity, having intermediate or varying conductivity, and being somewhat brittle in comparison to metals. Some examples of metalloids are boron, silicon, germanium, arsenic, antimony, tellurium, and astatine.
