C'mon lets go!!
We decided to go swimming...
I discovered the nucleus...
No it's fine to swim
Don't go swimming! There is something in there...
This is new... I guess the bird was right!
No! I'm shrinking into what looks like an atom
I was shrunk inside an atom...
I grew back into life size...
What are you talking about? I'm not changing!
I told you!!
Valance electrons are the electrons on the outermost shell. Oxygen has 6
We said goodbye and went home!
I travelled in the electron shell...
Oxygen has 8 electrons which are placed on the electron shells
The electrons have negative charge (-1)
This is an oxygen atom (O symbol) because it has an electron configuration of 2,6
What else can you see?
Oxygen has 8 protons and its atomic number is 8 as it is calculated by the number of protons
This is the nucleus where the protons and neutrons are located
The atomic mass is the number of protons and neutrons, oxygen has a mass of 15.999 meaning oxygen has 7.999 neutrons
Im growing back to life size!
Oxygen is located on the periodic table in period 2 and group 16
On the periodic table, periods are the rows (across) and group are the columns (down)
Oxygen is a non-metallic element on the periodic table
Okay, let's just get out of here!
Did you know that Oxygen was discovered in 1772 by a Swedish chemist, Carl Wilhelm Scheele
Well that was a strange Sunday!
