|Composition||16 protons, 10 neutrons, 9 mosirons|
Ertenium is one of the new chemical elements recently discovered in a meteor. It has previously unknown subatomic particles mixed with normal particles, like the mosirons.
At high speeds, it easily disintegrates, generating fatal gamma rays in every direction.
At really low speed, the atoms collapse in a fusion process and a giant nova-like explosion occurs.
