I got bored and decided to play the password game-
Rule 18 is: The elements in your password must have atomic numbers that add up to 200.
The current elements I have are: Ne, V, W, Re
I don't know what any of this is- I failed chem but please help ;-;

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 ].
Final answer:
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.
Explanation:
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.

pOH = -log(8.6 x 10 ^-5)
pOH = 4.07
To calculate the pH we use the relation of pOH and pH, expressed as:
14 = pOH + pH
pH = 14 - 4.07 = 9.93
pH = -log [H+]
[H+] = 10^-9.93 = 1.16 x 10^-3 M

B.)The atom consists of a nucleus with electrons orbiting randomly around it.
C.)The atom consists of a nucleus with electrons orbiting at specific energy levels. Absorbed photons cause electrons to jump between energy levels.
D.)The atom consists of a nucleus surrounded by a region containing electrons. Electrons cannot be located exactly within this region, but the probability that they will be found in an area can be stated.
