What two things do valance electrons control

Explanation:

Now using this information, we are looking for which has a full outermost shell AKA full capacity of valence electrons. For the 1st element, it should have 2 because the inner shell is also the outermost in this case. Since only 1 valence electron is present, it is not full. The second element, has 2 shells and thus should have 8 in the outermost shell, but only 3 are present in this case. So its not the 2nd one. The third atom does satisfy the conditions- making it the answer. The fourth is wrong because 3 shells are mentioned and so the outermost would need to have 18 valence electrons.

hopefully this helped, it took me age to write ahah

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
