[noble gas] ns2(n-1)d10np1 has just one unpaired electron because the np1 indicates that only one electron is present on a p sublevel. [noble gas] ns2(n-2)f6 has two unpaired electrons because the f sublevel can hold up to 14 electrons, but here only 6 are present.
1. noble gas: This part represents the electron configuration of a noble gas that precedes the given element. Noble gases have completely filled electron shells, so this part is essentially a placeholder for a fully filled electron configuration. 2. ns²: This signifies that there are two electrons in the s subshell. 3.
The noble gas notation [Rn] represents the electron configuration of the noble gas radon (Rn), which is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6. This notation is used to indicate that the electron configuration of the element in question is the same as the noble gas configuration of radon, followed by additional electron ...
More answers. AnswerBot. ∙ 5mo ago. The noble gas in period 5 is xenon, which is located in Group 18 of the Periodic Table. It has an atomic number of 54 and is known for being chemically inert ...
The noble gasses are the elements in the right most column of the Periodic Table. They are helium, neon, argon, krypton, xenon, and radon. Xenon is the noble gas on period 5.It has atomic number ...
The noble gas among the options given is argon. Noble gases are mostly nonreactive due to their fully filled valence shells. Explanation: Out of the options given in your question: A) oxygen B) chlorine C) bromine D) argon E) nitrogen, the noble gas is D) argon. Noble gases, which include helium, neon, argon, krypton, xenon, and radon, are ...
The noble gas notation for an element with valence electrons in the 5s subshell is [Kr]5s^1. Explanation: The noble gas notation is a shorthand representation of the electron configuration of an element, using the symbol of the noble gas that comes before it in the periodic table and placing the valence electrons in the appropriate subshell.
- Option B: Oxygen (O) is also not a noble gas. It is a highly reactive element that readily forms compounds with other elements. - Option C: Nitrogen (N) is not a noble gas either. It is a diatomic molecule that is relatively unreactive under normal conditions, but it is not classified as a noble gas. - Option D: Argon (Ar) is indeed a noble gas.
This is because the unpaired electrons can interact with other atoms or molecules to form new bonds. In the case of [noble gas]ns2 (n−2)f6, the three unpaired electrons in the (n-2)f subshell make this element highly reactive and able to form a variety of compounds with other elements. Overall, the number of unpaired electrons in an element's ...
