Explanation:
Nuclear fusion produces more energy with less radioactive waste compared to nuclear fission process.
- In nuclear fission, a radioactive decay occurs in which a heavy nucleus spontaneously disintegrates into two lighter nuclei and several neutrons with the release of energy.
- Nuclear fusion occurs when small atomic nuclei combines into larger ones with the release of a large amount of energy.
- Instability of a nuclide is enough to start up a nuclear fission reaction. In some instances, a heavy nuclide is bombarded with another nuclide.
- In nuclear fusion, the activation energy required to start up is very great.
Nuclear wastes emanating from nuclear fusion process is least compared to that of nuclear fission.

An example of accurate but not precise would be 3 people weigh a 10g sample. the weights are 0g, 10g, & 20 grams. the scale is way off but the weights average to the right thing.
precise but not accurate would weighing a 10g sample 3 times and getting 5.5, 5.4, & 5.5. they'e all incredibly similar therefore precise but its nowhere near 10, so not accurate.
neither precise nor accurate would be 3 weights being 10, 20, &30. It averages wrong and is imprecise.
Answer:
Case 1:
X = Any element from Group I
i) H
ii) Li
iii) Na
iv) K
v) Rb
vi) Cs
Y = 1
Case 2:
X = Any element from Group II
i) Be
ii) Mg
iii) Ca
iv) Sr
v) Ba
vi) Ra
Y = 2
Case 3:
X = Any element from Group III
i) B
ii) Al
iii) Ga
iv) In
v) Ti
Y = 3
Explanation:
The general formula given is as follow,
XCly
So, if X has +1 oxidation state, then it will require only one Cl atom with oxidation number -1 to form a neutral compound, therefore, y = 1.
If X has +2 oxidation state, then it will require two Cl atoms with oxidation number -1 to form a neutral compound, therefore, y = 2.
If X has +3 oxidation state, then it will require three Cl atoms with oxidation number -1 to form a neutral compound, therefore, y = 3.
