Ernst is the metalloid with the lowest atomic mass. Highho and terriblum are in Group 4A. Terriblum has more protons than highho. Yazzer touches the zigzag line, but it’s a metal, not a metalloid. Yazzer has 13 protons. (Clue: The alien Metalloids begin in Group 3A, period 2 just like the metalloids on Earth’s PT) ................
