Noble Gases
are colorless gases that are extremely un-reactive. Because they do not readily combine with other elements to form compounds, the noble gases are called inert. The family of noble gases includes helium, neon, argon, krypton, xenon, and radon.
Is Group 18 not reactive?
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.
Does Group 18 react with other elements?
The group of elements
Do noble gases react with anything?
If there is one half-remembered chemical fact that most of us carry from our schooldays, it is that the
inert or “noble” gases do not react
. … The theory of chemical bonding explained why. The noble gases have full outer shells of electrons, and so cannot share other atoms' electrons to form bonds.
Why are the elements in Group 18 unreactive?
Group 18 of the periodic table contains the noble gases. … Noble gases are
highly unreactive due to their full outer shell of electrons
. Having a full valence shell of 8 electrons means that the atom is already in its most stable state, and thus, there is no need for the atom to lose or gain electrons.
What is the other name for Group 18 elements?
Noble gas
, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson

Is nitrogen a noble gas?
On the other hand,
nitrogen is not a noble gas
. Two nitrogen atoms make up the nitrogen molecule (N
2
), so it has no free electrons like Argon and thus the same properties of a noble gas under nearly all uses. Indeed, nitrogen, which makes up 79.1% of our atmosphere, is very unreactive.
Why is argon a noble gas?
The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that,
in general, they don't react with anything
. For this reason they are also known as inert gases
What is the other name for Group 17 elements?
Halogen
, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine
What is Group 2 called?
Group 2A (or IIA) of the periodic table are the
alkaline earth metals
: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). … In most cases, the alkaline earth metals are ionized to form a 2+ charge.
Why the elements of group 17 are very reactive but the elements of group 18 are stable?
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.
What is 4 group 18th element called?
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson
What element is in Group 18 and Period 6?
| Group 1 18 | Atomic # Name 55 Cs 86 Rn |
|---|
Which is the most reactive element of the group 17?
Fluorine
is the most reactive of the halogens and, in fact, of all elements, and it has certain other properties that set it apart from the other halogens. Chlorine is the best known of the halogen elements.
