Which among Following is a noble gas?

Which among Following is a noble gas?

Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

What do you think the noble gases are placed in a separate group Class 10?

Noble gases are placed in a separate group of the periodic table because they are inert elements. They are unreactive as their valence shells are completely filled with electrons. Their properties are different when compared to all the other elements.

What do you think the noble gases are placed in a separate group Name any two noble gases?

Noble gases like helium (He), Neon (Ne), and Argon (Ar) are chemically inert and are present in atmosphere in extremely low concentrations. Thus owing to their similar inert behaviour and similar electronic configuration, they are justified to be placed in a separate group.

Where noble gases are placed in periodic table?

The noble gases are another family of elements, and all of them are located in the far right column of the periodic table. For all of you budding chemists, the far right is also known as Group Zero (Group 0) or Group Eighteen (Group XVIII).

Why is hydrogen in the first group?

Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. Because hydrogen is a nonmetal and forms H- (hydride anions), it is sometimes placed above the halogens in the periodic table. Hydrogen also forms H2 dihydrogen like halogens.

Which of the following is the correct noble gas distribution for chlorine?

Noble Gas Configuration

Element Name Symbol Noble Gas Electron Configuration
Phosphorus P [Ne]3s23p3
Sulfur S [Ne]3s23p4
Chlorine Cl [Ne]3s23p5
Argon Ar [Ne]3s23p6

What is the definition of noble gas configuration?

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium’s noble gas configuration becomes [Ne]3s1.

What is special about the electron configuration for noble gases?

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.
