Question

What is redox?

i heard about it but my teacher cant teach us because we are till in sub atomic particles

Answer 1

This is formal electron transfer between species.

Explanation:

See here and here. Reduction is conceived to be the gain of electrons, and oxidation the loss of electrons. Redox chemistry is involved in corrosion, and thus is the subject of much research. Anyway, I would wait to your teacher introduces the topic, or at least first read the chapter in your text.
