Octet-A group of 8 things or people
Explanation:
The halogen family and noble gases are similar in just one particular way, they are groups of non-metals. All members of these two groups are categorized as non-metals.
Here are some of the differences between them;
- Halogens have 7 electrons in their outermost shell whereas noble gases have 8 electrons in theirs.
- Halogens are highly reactive elements, noble gases are non-reactive.
- Halogens are made up of electronegative elements where as noble gases are neither electropositive nor electronegative.
<h2>Nuclear Fission and Nuclear Fusion - Option C</h2>
Nuclear fission and nuclear fusion both of these processes can provide energy. Nuclear fission is the process in which heavy nucleus splits into smaller parts. When they split into smaller particles then it releases energy.
On the other hand, nuclear fusion is the process in which small particles fuse together to form a heavy nucleus. With the formation of heavy nucleus, it also provides energy.
Therefore, both these processes release or provide energy.
