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. The name was given by physicist Michael Faraday for the substances that allow a current to pass ("go") between electrodes in a solution, when an electric field is applied. It is the transliteration of the Greek participle ἰόν, ión, "going".
An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion.
An anion (−) ( /ˈæn.aɪ.ən/ AN-eye-ən), from the Greek word ἄνω (ánō), 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).
A cation (+) ( /ˈkæt.aɪ.ən/ KAT-eye-ən), from the Greek word κατά (katá), meaning "down", is an ion with fewer electrons than protons, giving it a positive charge. Since the charge on a proton is equal in magnitude to the charge on an electron, the net charge on an ion is equal to the number of protons in the ion minus the number of electrons.
I should have treated you a bit warmer
Kept you over here in my corner
After all is said and done
You still got me on the run
A bit longer
Every day and night
I wish I had tried
A bit harder
I should try a little bit harder
I should try a little bit harder
Looking back
I could have been smarter
Maybe given time
We could get it together
I've got memories of our time
Playing over in my mind
I cannot forget
I wish I could make it right
Maybe if I could turn back time
We could have made it if I tried
If I tried
I should try a little bit harder
I should try a little bit harder
I couldn't meet with your demands
So much I couldn't understand
All the good things that we had
Slip like water through my hands
Was I blind that I didn't see
That you needed more from me
How much we had to try
We could make it if I try
I should try a little bit harder
I should try a little bit harder
I should try a little bit harder
