Opinion Onion (Part 2 of 365).


An ‘ion’ is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.

An ‘anion’ (pronounced /ˈænaɪən/; an-eye-on), from the Greek word ἀνω (anο), meaning "up", is an ion with more electrons than protons, giving it a net negative charge (since electrons are negatively charged and protons are positively charged).

An ‘onion’ is a bulbous plant (Allium cepa) cultivated worldwide as a vegetable.

An ‘opinion’ is a belief or conclusion held with confidence but not substantiated by positive knowledge or proof.

It is also a root vegetable.
