Noble gases are least reactive because they have a full shell
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
noble gases are least reactive
Argon is considered a noble gas and is known for its very low reactivity. It is colorless, odorless, and non-toxic, making it one of the least reactive gases.
Most elements are non reactive to noble gases.
No, they are the least reactive gasses.
The Noble Gases.
Generally, the least reactive elements are the noble gases.
Yes, argon is a noble gas. It is a colorless, odorless, and non-reactive gas that is part of the noble gas group on the periodic table.
Fluorine is considered the most reactive gas because of its high electronegativity and tendency to gain an electron to achieve a stable electron configuration. It readily reacts with almost all other elements, including noble gases.
The Noble Gases.
Noble gases are, for all intents and purposes, unreactive - there are a few noble gas compounds but you have to really work at it to convince noble gases to form bonds. Fluorine is an extremely reactive gas, hence it is not a noble gas. It is a halogen - the most reactive halogen of them all.
