Reactive
Lead is a moderately reactive metal. It reacts slowly with air and water, but does not react as vigorously as highly reactive metals like sodium or potassium.
It is a nonreactive metal
It is not true; many metals are very reactive and several nonmetals are nonreactive.
Ytterbium is a reactive element, but it is primarily reactive with air and water, rather than being highly reactive in general. It is not as reactive as some other metals like alkali metals such as sodium or potassium.
Non-reactive, along with all other noble gasses.
It is reactive, but does not react to most chemicals.It does react to chlorine and aqua regia.
No, Potassium is one of the most reactive metals.
Potassium is the most reactive element among potassium, iron, and aluminum. It is a highly reactive alkali metal that readily reacts with water and air. Iron is moderately reactive, while aluminum is reactive but forms a protective oxide layer that prevents further reaction with the environment.
Plutonium is a very reactive metal: the Pauling electronegativity is 1,28.
no, it is very reactive.
Because it is a noble gas, it is no reactive, as all its electron shells are filled.
Non-reactive means there is no response when exposed to stimulus or to other materials.
