Barium: The Metal with a Double Positive Attitude
Hey there, science enthusiasts! Today, we’re going to dive into the fascinating world of barium, an element that’s got a double positive charge and a whole lot of personality.
Barium is a member of the alkali earth metal family, which means it’s a group of metals that are known for their reactivity and their ability to form ionic bonds. Barium’s atomic number is 56, which means it has 56 electrons buzzing around its nucleus. When barium interacts with other elements, it tends to lose two of those electrons to achieve a stable oxidation state of +2.
