If I were to create a password out of elements of the periodic table such that the sum of them would add upto 200 ,
I would be using these elements
Berillium = 4 [Be]
Sulphur = 16 [S]
Uranium = 92 [U]
Nitrogen = 7 [N]
Hydrogen = 1 [H]
Iodine = 53 [I]
Neon = 10 [Ne]
and the password would be " Be SUNSHHINe " which adds upto [4 + 16 + 92 + 7 + 16 + 1 + 1 + 53 + 10 = 200 ].
The given elements' atomic numbers add up to 182. To meet the requirement of Rule 18 (total of 200), you need elements that add up to 18 (200-182). By adding Fluorine (F) and Argon (Ar), both with atomic numbers of 9, you can reach the required total.
The periodic elements provided in the question are Neon (Ne), Vanadium (V), Tungsten (W), and Rhenium (Re). Their respective atomic numbers are 10, 23, 74, and 75. If you add these atomic numbers together, the total is 182. This means you need elements that will add up to 18 (200-182) to meet the requirement of Rule 18. Adding Fluorine (F) with an atomic number of 9 and Argon (Ar) with an atomic number of 9 can help you reach this required total.
To summarize:
Neon (Ne) = 10,
Vanadium (V) = 23,
Tungsten (W) = 74,
Rhenium (Re) = 75,
Total so far = 182,
Your password needs atomic numbers total = 200,
You're short of = 200 - 182 = 18.
Adding Fluorine (F) with atomic number 9 and Argon (Ar) also with atomic number 9 gives = 9+9 = 18.
