Answer:
The Girl will go up and the Boy will go down
Explanation:
Total mass = x
It would be: x*32.38/100 = 32
x = 3200/32.38 = 97.56
Atomic mass of (OH)2 = 34
So, remaining mass = 97.56-34 = 63.56
which is approximately equal to mass of copper
So, we can say m is copper here, and formula of the compound would be Cu(OH)2
Isotopes are basically from the same element. In terms of subatomic particles of the element, the isotopes will then basically have the same number of protons. The electrons also have to be same in number given that the elements are in neutral charges.
We are then left with neutrons, which is one of the subatomic particles residing in the nucleus of an atom.
Thus, the answer is NEUTRONS.
