In a battery, the metal ions in cathode gains electrons while the anode loses.
Everything in the world is harmful if in large amounts, and this includes all-natural fruits, water, etc. , because the dose (amount) makes the poison (lethal).

An organic functional group with a carbonyl in the middle and other groups on the 2 other sides (usually represented as R and R')
The most common ketone is acetone, which is used in fingernail polishes.
A dimethyl derivative of xanthine, structurally similar to theobromine.
Theophylline is used in therapy for respiratory diseases.
A class of organic compound with the formula of R CHO, with the R being an organic functional group.

some kind of compounds containing conjugated double bonds, like benzene.
According to Huckel's rule, aromatic compound needs following properties:
-The structure is planar (no sp3 carbons)
-There is a cyclic ring in the structure
-Has 4n+2 electrons in the pi system
An organic functional group similar to amine, except a carbonyl is next to it. (Its formula is RC(O) NR2)
However, amide is very different to amines due to the delocolization of the lone pair to oxygen. This makes amides unreactive.
