Which element is classified as a noble gas? o, n,cl, xe?

Xe

Explanation:

Noble gas are the elements which have their valence shell complete and are almost inert in nature. They have very low reactivity and they exist in gaseous form.

The electronic configuration of oxygen is:-

The electronic configuration of nitrogen is:-

The electronic configuration of chlorine is:-

The electronic configuration of xenon is:-

Since, Xenon has its valence electron having 8 electrons and thus, it is a noble gas.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
