At 1.18 you say it needs one more electron. But where does it get it from?

Good question! It gets the extra electron from an atom like sodium that needs to lose an electron. So when sodium and chlorine react together, sodium gives an electron to chlorine.

But I don't understand the situation. Where does the sodium appear from?? Are they floating around in the air ?

No it’s if you have a piece of sodium and heat it up in a jar of chlorine. You have to put them together. Check out my video on alkali metals and Chlorine in playlist C2 👍

@@michaelrowland-us3he It also happens in nature if the right 2 elements come together. For example Iron will react with oxygen in the air to make iron oxide (rust). The iron atoms will give away electrons to the oxygen atoms.
