Why noble gases unreactive

Which group of elements is listed in order of increasing electronegativity? Of the following elements, which has the highest electronegativity? Question f6b1f. Which element in the periodic table is the most electronegative?

See all questions in Periodic Trends in Electronegativity. Impact of this question views around the world. When this happens, the electrons jump to a higher energy level. When the electrons return to their original energy level, they give off energy as light. Different noble gases give off light of different colors. Neon gives off a reddish-orange light, like the word "Open" in the sign below.

Krypton gives off violet light and xenon gives off blue light. Watch the video about noble gases at the following URL, and then answer the questions below. Compare and contrast the reactivity of the elements helium, neon, argon, krypton, and xenon. Describe how the mass of noble gases changes from the top to the bottom of group What are Noble Gases?

Chemical Properties of Noble Gases Noble gases are the least reactive of all known elements. Noble Gases and the Octet Rule Because the noble gases are the least reactive of all elements, their eight valence electrons are used as the standard for non-reactivity, and to explain how other elements interact. Some Uses of Noble Gases Have you ever had helium balloons like those in the elephant image? Summary Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table.

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds. Another preference of smaller atoms to have two electrons in the outermost electronic shell is called as duplet rule.

Sometimes, this Duplet rule is also known as the duet rule. This last group is known for the complete number of electrons in valence shells i.

They are also known as inert gases for being inert to chemical changes or reactions. Noble gases, being inert, have completely filled electronic shells making their electronic configurations stable or standard. Normally, the noble gases compounds are highly unstable.
