The atoms allways try to get the octet on their outest layer. I mean the group of 8 electrons. I cant put it well in words since I lack english words in chemistry. But you should know what I mean.
I’m not fluent in english either, but I think I know what he ment…
All the chemical elements tend to have 8 electrons in their valent(is this the correct word?) shell… for example, noble gasses all have electron configuration such that their last shell carries 8 electrons, that is why they are not reactive… All the other elements tend to make a chemical bond such that they get 8 electrons, that state is energy balance or something like that…
well, perhaps i should allow a native english speaker to explain this
2 - divide even numbers by this
3 - holy trinity (father son holyghost)

5 - senses
7 - wonders of the world
CDEFGAB (7 notes)

9 - the end of single digit land
10 - basis of numbering

13 - bakers dozen
moons per year
so, atoms have electrons, and those in the outermost shell are called the ‘valence’ electrons. atoms like to have 8 of them, because all atoms wanna be just like the noble gasses. So, they share(covalent bond), or trade electrons(ionic bond) to get 8 of them.
