A chemist must prepare 400 mL of 1.00M of aqueous potassium iodide working solution. He'll do this by pouring out 1.82 mol/L som
e aqueous potassium iodide stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in of the potassium iodide stock solution that the chemist should pour out. Round your answer to significant digits.

Sulphur is located in the third period and group 16. The general electronic configuration of group 16 is therefore the maximum number of valency electrons in group 16 is 6. The electronic configuration of sulphur is [Ne]
. Sulphur has six valency electrons whereas sulphur can have more than eight electrons in its valency shell as it have an empty d-shell electrons can accumulate in the empty d-shell. The complete d-shell and the
orbital will be empty. As each orbital can accept 2 electrons, sulphur can have 12 valency electrons in its valency shell.
