Noble Gas Configuration For Radium

The symbol for xenon (xe) would be a part of the noble gas note for the chemical element antimony. cesium. radium. uranium.

Answers

The noble gas notation is the short or abbreviated course of the electron configuration.

Information technology means that you use the symbol of the previous noble gas equally part of the electron configuration of an element.

The gas noble previous to antimony is Kr, and so you exercise not use Xe to write the electron configuration of Sb.

The gas noble previous to radium is Rn, and then you practice not utilize Xe to wirte the electron configuration of Ra.

The gas noble previous to uranium is Rn, so y'all do not apply Xe to write the electron configuration of U.

The gas noble previous to cesium is Xe, so you use Xe to write the noble note for Sb. This is it: Cs: [Xe] 6s.

cesium

The ga

Explanation:

To write the electronic configuration of an element using the preceding element of group 0 configuration, we simply use the noble gas in the previous period of that particular element. We do not use the noble gas of that period in which the element belongs to simply the one in the preceding group.

A is wrong

This is considering the noble gas in the preceding menses is krypton.

In fact, the electronic configuration is [Kr] 4d105s25p3

C is wrong

The noble gas in the final period here is Radon. The electronic configuration of Radium in fact is [Rn] 7s2

D is incorrect

The noble gas in the final period before the period of uranium is Radon besides. In fact, the electronic configuration of the element is [Rn] 5f36d17s2

B is correct, the actual electronic configuration of the element Cesium is [Xe] 6s1

The question is incomplete. The complete question is:

The symbol for xenon (Xe) would exist a part of the noble gas notation for the element antimony. cesium. radium. uranium.

cesium

Explanation:

The electron configuration of elements could be written in autograph format. This shorthand format simply indicates the noble gas cadre filled by the valence electrons of the element.

Among the elements listed, only caesium has a xenon core. The electron configuration of caesium is:

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s1 which can be written in shorthand form as [Xe]6s1. Hence the answer.

All of the elements from Cs to At
