What are the seven noble gases?
There are only six noble gases: helium, neon, argon, krypton, xenon and radon. The seventh noble gas, ununoctium (atomic number 118) has been proposed but its existence has not been proven so far.
How many elements are inert gases?
Six noble gases (group 18), and Nitrogen (N2) gas are all inert. They are all different elements, so: 7
What are substances with which argon combines with?
Argon is one of the Noble Gases, so it is inert, meaning it has a full outer shell and therefore never combines with any other element. The noble gases are also called the inert gases. The six noble gases are helium, neon, argon, krypton, xenon, and radon. They are members of group 18 of the periodic table (right side). They are odorless, colorless gases
Why noble gases are highly reactive?
Noble gases are not reactive. They are inert. That's why they are called noble gases. Just as the human nobility does not lower itself to associate with the lower classes, so do noble gases not combine with lesser elements. They remain aloof.
What group of the region shown on the periodic table contains mostly elements that are gases at room temperature?
The so-called noble or inert gases are in Group 18, the last group on the right of the periodic table of the elements.
Why are the elements helium argon and neon called inert gases?
As we all know that noble gases are also called INERT GASES, so the subgroup VIII of GROUP 'A' contains only noble gases and inert gases so helium and neon are also in VIII-A so they are inert gases.
How many electrons are present in the valence level for all noble gases except helium?
There are eight in all noble gases (except helium) because that forms a "full level" so that they are noble gases and not reactive.
What are the gases that are considered inactive?
They are called noble or inactive gases because they do not react with other elements under ordinary circumstances. They include helium, neon, argon, etc.
Why is a noble gas inert?
Noble gases have a stable electron configuration. So they are less reactive.
What is the main characteristic that all the noble gases have in common?
the noble gases have octet configuration ie they have 8 electrons in their outermost shell ,so they are stable
What group of the periodic table are helium and neon in?
They belong to group 8A, more commonly referred to as the "noble gases." These gases are so named because they are extremelynonreactive,referring to nobility's preference for not dealing with any of the lower classes.
What makes noble gases noble?
The so-called noble gases have the outer electron shell full, with 8 electrons; this structure lead to a very low chemical reactivity but now they are not considered as inert elements.
