Question

which element from the reactivity series form atmospheric oxide

Answer 1

Answer:

Hey mate! I have the answer. May be it is correct.

An amphoteric oxide is a substance that can chemically react as either acid or base. Aluminium oxide shows acid and basic properties of oxide so it is amphoteric. Thus, Al

2O3entails the marking point at which a change over from a basic oxide to acidic. So Aluminium forms atmospheric oxide.

Answer 2

${ \large {\underline {\sf {\red{Amphoteric \: oxides:}}}}}$

Amphoteric oxides are the metal oxides which react with both acids as well as bases to form salt and water. Some examples of amphoteric oxides are aluminum, tin, zink, beryllium etc.

${\underline{\sf {\color{navy}{Properties \: of \: amphoteric \: oxides:}}}}$

• Amphoteric oxides has both properties of bases as well as acids.
• When they react with acids, they show properties of bases and form salt and water.
• And when they react with alkalis, they show the properties of acids.

Which element from the reactivity series form atmospheric oxide?

${ \huge {\underline{ \sf {\blue{Answer:}}}}}$

Aluminium oxide us an amphoteric oxide, which mean that it can react with both acids as well as bases. For example it will react with hydrofluoric acid and sodium hydroxide and will act as an acid in the presence of base and a base in the presence of acid and will neutralise the other and result in the formation of salt.

Chemical formula of Aluminium oxide is$\sf{Al_2O_3}$

And its molar mass is 101.96 g/mol.
