Frage 3
Frage
An [blank_start]ion[blank_end] is when there is an atom with more or less electrons that the usual. Usually, in a stable atom, there are the same number of protons as electrons.
[blank_start]Cation[blank_end] - more protons, less electrons >> [blank_start]positive[blank_end]
[blank_start]Anion[blank_end] - less protons, more electrons >> [blank_start]negative[blank_end]

Cation
-
Anion
-
