Please I want brainliest.
Reason:
The size of the ions follows the order:
Negatively charged ion > Neutral atom >
Positively charged ion
This is because of the size of ions increases when the electrons are added to the outermost shell of an atom.
This happens due to the increase in
electron-electron repulsion.
Moreover, when the electrons are removed from an atom, then the affective nuclear charge that is experienced by the outermost electron increases.
Thus the size of the positively charged ion is least.
That statement is true
it was easy to organize 'all' the elements in a group of threes because back then they only knew about 15 - 20 elements
hope this helps
