What is the main characteristic of family 18 elements?
The main characteristic of family 18 elements is that they are known as the noble gases. They have a full outer electron shell, making them stable and unreactive. They are colorless, odorless, and tasteless gases at room temperature.
What are the main group group elements?
the noble gases
What are the 4 main categories of elements found on the periodic table?
- The Group 1A elements are called alkali metals. - The Group 2A elements are called alkaline earth metals. - The nonmetals of Group 7A are called halogens. - The Group 8A elements are called the Noble Gases
Why does the Fe does not belong in the noble gases?
Iron (Fe) does not belong in the noble gases because it is a transition metal, not a noble gas. Noble gases have a full outer electron shell, making them stable and unreactive. Transition metals like iron have partially filled d or f orbitals, and they can form ions and participate in chemical reactions.
Why are noble gas called inert gas?
Nitrogen is typically inert for most common uses. Only the noble gases (8A) are truly inert, though they are rare. Nitrogen is a diatomic in natural state, meaning that two nitrogen atoms are stuck together. This configuration gives both atoms enough electrons to fulfill the octet. In order to get the nitrogen to react with anything the bond must be broken. Since reaction (usually) happen spontaneously when a lower energy state results, it is unlikely for the nitrogen to break on its own.

What are the main noble gases?
Helium, Neon, Argon, Krypton, Xenon, Radon, Ununoctium
What are the three main features of noble gas?
They are all unreactive They are all gases They are all monatomic
How do the physical and chemical properties of the haogens compare with those of the noble gases?
noble gases really are just that: noble. they dont react to things easily. halogens on the other hand, do react extremely easily. that is one of the main differences between the two.
What are the common gases in the galaxy?
Hydrogen and helium are the two main gases in the Universe.
In the periodic table what group is ignored?
The f-block, or inner transition metals, are sometimes ignored in the main body of the periodic table due to their size. These elements are typically placed below the main table to conserve space, but they are still part of the overall periodic table.
What group of elements does the p block on the periodic table contain?
halogens & noble gases
What are the two main gases?
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
What are the main gases in the atmosphere of earth?
This is the approximate composition of the atmosphere today:78% Nitrogen21% Oxygen0.004% CO2The rest consists of Noble Gases, as well as traces of other various gases, like Ammonia and Carbon Monoxide.
