They can be both. PTFE and Polyethylene are very inert. Poly(acrylic acid) is very reactive.
Unreactive or non-reactive.
Chlorine is very reactive.
Calcium is a reactive chemical element.
It is a noble gas and so very unreactive.
It is not true; some metals are not so reactive and noble metals are practically unreactive.
Unreactive
Mostly it is unreactive.
Unreactive or non-reactive.
Chlorine is very reactive.
They are generally unreactive as their orbitals are completely filled.
No. Lithium is highly reactive.
Calcium is a reactive chemical element.
It is a noble gas and so very unreactive.
It is not true; some metals are not so reactive and noble metals are practically unreactive.
Alkali metals are very reactive metals.
Nobel gases are very unreactive.
they contain unreactive atoms
