Column tells you how many valence electrons there are
Row tells you how many layers (circles)
Sodium (Na) has 1 valence electron
Sodium (Na) is the 3rd row so there's 3 circles
Has 11 total electrons
Bohr models show ALL ELECTRONS
The first shell can only hold 2 electrons
Every shell after that can hold 8.
So the first shell has 2 electrons, second one has 8 electrons, and the third one has 1.
2 + 8 + 1 = 11

Answer:
was the concentration of the original solution.
Explanation:
(Dilution)
where,
are molarity and volume of non diluted sample.
are molarity and volume of diluted sample.
(1μL=0.001 mL)
Substituting all values :
was the concentration of the original solution.
