Unreactive
unreactive nonmetals are called noble gases
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
The most characteristic property of noble gases is their inertness or lack of reactivity due to having a full outer electron shell. This makes them stable and unreactive under normal conditions.
noble gases are least reactive
No. They are the least because their energy levels are full.
Nobel gases are very unreactive.
They are generally unreactive as their orbitals are completely filled.
unreactive nonmetals are called noble gases
Noble gases have completely filled outer electronic configuration. Hence they are non-reactive.
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
The full octet means the element is inert (non-reactive.)

Correct.
noble gases are least reactive
No. They are the least because their energy levels are full.
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
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.
