Hello to my fellow forum members, of late I have not looked at chemistry, so off the top of my head, will see if what I remember is correct, without looking it up.
Below are several statements, could you please correct me if my memory serves me wrong.
1. Chemistry is the study of Atoms and their reactions, but is focused only on the electron and not the nucleus of the an Atom.
2. You can only have 7 electron layers
3. The layer of the electron shell closest to the nucleus of an atom is called the 1s layer.
4. The second layer is called 2s
5. The 3rd layer then becomes the P layers.
6. The 3rd layer is the Pi-bonding layers
7. Electron layers can contain no more than 8 Electrons
8. Mostly chemical reactions involve H.
9. Chemical bonding can have different shapes such as the chair and boat formation.
10. If I put salt in water, the salt is salute.
11. h20 is 2 hydrogen and 1 oxygen
12. Co2 is one carbon and 2 oxygen
13. Gases have different densities and different buoyoncy
14. He , is the most buoyant gas
15. H + H makes He
16. Energy is needed for the bonding process
I thank you in advance for corrections.
