We might get confused between cations and anions. How do we remember that cations are positive?
An easy way is to remember
The 't' in the middle of 'cation' can be imagined as a representation of the '+' sign.
Another method is just to remember that Anions are negative, which is easier because they contain the letter 'n' ( imagined for 'negative'). There is no need to find a memory hack for cations again as it will be the opposite of 'Anions'.
