Answer:
[Cl-18]⁻ & [Cl-20]⁻
Explanation:
By definition isotopes are elements with the same number of protons by different number of neutrons. Elements X-18 & X-20 have 17 protons and represent Chlorine isotopes Cl-18 & Cl-20 each with 17 protons and 18 electrons to give the isotopes a -1 oxidation state. Both isotope of chlorine have 7 electron in its valence shell and 10 electrons in its core structure. Gaining 1 electron fills the valence octet and establishes a -1 oxidation state.

Answer:
Explanation:
1 = A
Sublimation is the process where by a sample is heated to pass through solid phase to gaseous phase without the intermittent liquid phase. Example of substance that sublime is camphor.
2 = D
Decantantion
5 = F
Filtration is the process a liquid from solid using a porous material. This technique requires a set up and a good porous material eg filter paper.
6 = B
This technique is to separate a mixture of solids by converting them from solid phase to gaseous phase since they sublime.
3 = deposition.
The answer isn't in the option but deposition is the process of substance in gaseous phase to change into solid state without passing through liquid phase. Deposition is the opposite of sublimation.
4 = E
The answer is A it’s tall
