Apr 01, 2017 · It was not exceptional for an Irishman to consume ten pounds of potatoes a day and very little else. On this diet, the Irish, without the benefit of medical science, hygiene, industrialization, or decent government, increased from 3.2 million in 1754 to nearly 8.2 million in 1845, not counting the 1.75 million who emigrated before 1846.”

Each period you go down increases the energy levels surrounding the atom (you can draw Bohr Models to show this is true). For example, H and Li (in group 1A) both have 1 valence e-, but H’s is in the first energy level, and Li’s is in the 2nd.

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)
