"Well, the atomic structure isn't changing. But it's a single element. Not only that but it's one that isn't found on the current periodic table. This is one heavy element if it hasn't been discovered before." She recorded the atomic data including its lattice structure into her computer, whatever it may be. "Let's see, what should we call it? Ooooh, how about... Celestium, since it comes from the sky?"
OOC: The lattice structure is how atoms are organized. Much like the atoms in a crystal.
