How would Mg change to gain a noble gas structure?
There is no such noble gas with the same electron configuration as helium ion. Helium is the first noble gas, is stable and does not form ions. There can be, however, other ions such as H- or Li+ that will have the same number of electrons as element helium.
To make barium sulfate crystals, you would typically mix a solution of barium chloride with a solution of sodium sulfate. This would cause a precipitation reaction in which barium sulfate crystals form. These crystals can then be collected by filtration, washed, and dried to obtain the desired product.
I think it would be easier to say what gases ARE noble gases. The six noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon. Any other elements are not Noble gases. This can include elements like Gold, Mercury, Calcium, Potassium, and barium.
A mole of any substance contains approximately 6.022 x 10^23 particles. For barium, this would be 6.022 x 10^23 atoms of barium.
How would Mg change to gain a noble gas structure?
Barium has 2 electrons in its outermost shell. To achieve a noble gas electron configuration similar to xenon, which has 8 electrons in its outermost shell, barium would need to give up 2 electrons. This would leave barium with a full outer shell and a stable electron configuration.

To isolate the barium sulfate, you would first filter the mixture to separate the solid barium sulfate from the remaining solution of sodium chloride. The collected barium sulfate can then be washed with distilled water to remove any impurities before drying it in an oven to obtain the pure compound.

Barium has 56 electrons. To make 8 electrons, it would need to lose 48 electrons to reach a stable electron configuration similar to a noble gas.
It is very reactive.
BaCl would not exist. BaCl2 would be Barium Chloride, though.
From the decomposition of barium phosphide (Ba3P2), barium (Ba) and phosphorus (P) would be formed.
Since barium sulfate and barium chloride have a 1:1 molar ratio, you would need the same amount of barium chloride as barium sulfate, so 100 grams.
The compound formed between barium and chlorine would be barium chloride (BaCl2). In this compound, barium has a +2 charge and chlorine has a -1 charge, so two chlorine atoms are needed to balance the charge of one barium atom.
