The atomic number of the undiscovered element is 168
Element 118 will have just filled its 7p orbitals. therefore the predicted element to fill completely up to its 8 p orbital would have to filled a whole set of s, p, d, f and g orbitals
That's another 2 + 6 + 10 +14 + 18 = 50 electrons
To determine the total number of quantum numbers we have to find
Nml × Nms
we have Nml × Nms = ( 2 + 1 ) × 2
8s + 8P + 7d + 6f + 5g = 2 + 6 + 10 + 14 + 18 = 50
The element right below should be
Z = 118 + 50
= 168
Hence the atomic number of the undiscovered element is 168

Answer:
The answer to your question is C₂HO₃
Explanation:
Data
Hydrogen = 3.25%
Carbon = 19.36%
Oxygen = 77.39%
Process
1.- Write the percent as grams
Hydrogen = 3.25 g
Carbon = 19.36 g
Oxygen = 77.39 g
2.- Convert the grams to moles
1 g of H ----------------- 1 mol
3,25 g of H ------------- x
x = (3.25 x 1) / 1
x = 3.25 moles
12 g of C ---------------- 1 mol
19.36 g of C ---------- x
x = (19.36 x 1) / 12
x = 1.61 moles
16g of O --------------- 1 mol
77.39 g of O --------- x
x = (77.39 x 1)/16
x = 4.83
3.- Divide by the lowest number of moles
Carbon = 3.25/1.61 = 2
Hydrogen = 1.61/1.61 = 1
Oxygen = 4.83/1.61 = 3
4.- Write the empirical formula
C₂HO₃
Is bubble chamber one of your choices? Bubble chamber sounds like a good fit for the question.
It is a compound because a compound is two or more different elements chemically combined.
Its true, By definition, an atom is electrically neutral<span> it has the same number of protons as it does electrons, plus some number of neutrons depending on the isotope</span>
