Answer:
Answer 1: there are 4 valence electrons in the Example A
Answer 2: The d subshell can hold up 10 electron: True
Answer 3: The element argon has 8 valence electrons.
Explanation:
<em>Answer 1:</em> The example A has four shells, and in the forth shell, it holds a total of 2 + 2 = 4 , so it has 4 valence electrons.
<em>Answer 2:</em> As you can see in the image, the d subshell has 5 different areas where you likely find a pair of electrons. In each area you can find until 2 electrons, so 5 x 2 = 10 electrons can be hold up in the d subshell.
<em>Answer 3</em>: Noble gases like argon have 8 valence electrons and its electron configuration is [ N e ] 3 s 2 3 p 6

Explanation:
This whole process is known as oxymercuration and demercuration.
First step is mercuration and second step is demercuration.
it is an electrophilic addition reaction and generally we take water as a solvent but here methnaol is given so instead of attacking water , methanol will attack.
In this reaction first alkene reacts with mercuric acetate (AcO–Hg–OAc)
and it formed ring with alkene because pi electron of alkene share it with mercuric acetate and there is no formation of carbocation and hence there will not be any rearrangement possible.
