Let's break down the clues:
-
The "tiny evil gnome or goblin" element on the periodic table refers to Gallium (Ga), which has 31 protons. Subtracting 6 protons from Gallium gives you 25 protons, which corresponds to Manganese (Mn).
-
The "lazier" element that has 18 electrons and is found on the far right side of the periodic table is Argon (Ar).
-
Finally, the f-block element that glows in the dark with an atomic number of 61 is Promethium (Pm).
Putting that all together:
- Manganese (25)
- Argon (18)
- Promethium (61)
So the answers are:
- Manganese
- Argon
- Promethium
