Classes of metals products with soft bases, which are bases with covalent bonds. The IUPAC Gold Book provides a more general definition of a class (a) metal ion, as "A metal ion that combines preferentially with ligands containing ligating atoms that are the lightest of their Periodic Group", and a class (b) metal as one that combines preferentially with ligands containing ligating atoms other than the lightest of their Periodic Group. Classes of metals Class A metals are metals that form hard acids. Hard acids are acids with relatively ionic bonds. These metals, such as iron, aluminium, titanium, sodium, calcium and the lanthanides,
Element Girl and joins the mission to the elevated coast of New Themyscira. After the death of Billy Batson, Emily uses her powers to protect the remaining children alongside Cyborg. Emily Sung appears in "DC Bombshells". Like Metamorpho's original powers, Element Girl (and Element Woman) could transform her body into any of the elements naturally found in the human body and shape them at her will. She can change her hair color using metals, and she can create silicate faces that fall off after a while. She uses the faces for ashtrays. She said she once tried to transmutate her body into
