Helium, Neon, Argon and if another Krypton.
What else can I help you with?
What class of element includes all of the elements that are gases at room temperature?
The class of elements that includes all elements that are gases at room temperature is the noble gases. These are located in Group 18 of the periodic table and include elements such as helium, neon, argon, krypton, xenon, and radon.
What percentage are the rare gases in the air?
The rare gases, also known as noble gases, make up about 1% of the Earth's atmosphere. This includes gases like helium, neon, argon, krypton, xenon, and radon. These gases are considered rare because they are present in very small concentrations compared to other gases like nitrogen and oxygen.
What periodic group does the element neon belong to?
Neon belongs to the noble gas group on the periodic table. Specifically, it is located in Group 18, which is also known as the noble gases or inert gases. These elements are known for their stable and unreactive nature.
What element family does hydrogen belong to?
Krypton belongs to the Noble Gas Family or the Inert Gas Family.
Group 8A also referred to as Group 18 elements on the periodic table share which characteristics?
The group 18 elements, also called the noble gases, are gaseous elements, completely nonreactive, with a full, stable valence shell. They were the last elements to be discovered because they're inert.
Are noble gases considered metals?
no. All noble gases are non metals
Where do the noble gases get their name?
These gases generally dont react with any other elements and hence are considered 'noble'.
Which gases are considered monatomic gases?
There are many gases that can be considered monatomic gases. Some of these gases are helium, neon, argon, krypton, xenon and radon and all of those gases are considered noble gases.
What elements are considered not very reactive?
Noble Gases
Why are the noble gases noble?
"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.
Which gas does not react with oxygen?
Noble gases are considered inactive and do not react with any other substance/element.
What is an alternative that correctly describes elements considered as noble gases?
Inert gases or group 18 elements.
What is the hardness of the noble gases?
it has no hardness ohk... then what exactly do you call solid oxygen?
Why are argon and krypton considered noble gases but not usually found in compounds?
Argon and krypton are considered noble gases because they have a full outer electron shell, making them stable and non-reactive. Since they already have a full outer shell, they do not readily form compounds with other elements. This lack of reactivity is what distinguishes them as noble gases.
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.
How active is noble gases?
Noble gases are chemically inert.
How are noble gases different than noble gases?
it's not
