To understand the difference between metals, semiconductors and electrical insulators, we have to define the following terms from solid-state physics: A possible crystal structure of Barium is body-centered cubic structure. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. The symbol of resistivity is usually the Greek letter ρ (rho).

We use cookies to ensure that we give you the best experience on our website. Barium(2+) is a barium cation, a divalent metal cation and a monoatomic dication. Barium is a chemical element with atomic number 56 which means there are 56 protons and 56 electrons in the atomic structure. Because of its high chemical reactivity, barium is never found in nature as a free element.
