Answer:
Explanation:
Given that:-
Moles of the salt, 
= 21 μmol
Also, 1 μmol = 0.001 mmol
So,
Moles = 0.021 mmol
Given that:- The volume = 200 mL
Also, 1 mL = 0.001 L
So, Volume = 0.2 L
Thus,
Answer:
[Ne] 3s2 3p2
Explanation:
Neon (Ne) is the noble gas right before silicon (Si).
Then right after neon is the 3s subshell. It has two electrons and is full.
After 3s comes the 3p subshell, and silicon only has two electrons in the 3p subshell (you can just count the electrons in each subshell on your periodic table).
The atomic number is based on the number of protons, so the atomic number would be 43
