Answer:
3rd option: AX + BY ⇒ AY + BX
Explanation:
The 2nd option is a single displacement reaction where one bound atom is displaced.
Logically, it would follow that a double displacemnt would be one where two bound atoms, i.e. X and Y, are displaced.
Explanation:
Xenon is a noble gas element that is highly unreactive. It has completely filled outermost shell and very stable on its own.
Xenon is an element with an atomic number of 54; it has an electronic configuration below:
[Kr] 4d¹⁰ 5s² 5p⁶
As we can see, the outermost energy shell, level 5; has a configuration of:
5s² 5p⁶
S is a sublevel with 2 electrons made up of 1 orbital
P is a sublevel with 6 electrons made up of 3 orbitals
These orbitals are filled in xenon and so it is stable and will not want to react with any other kind of atom.
This is why it is unreactive.
