Amphoteric is a chemical entity (ion or molecule) which can react as an acid but also as a base.
Compounds of beryllium, tin, aluminium, lead, zinc have amphoteric hydroxides and oxides.

Oxides that are both acids and bases?
Such oxides are known as the amphoteric oxide they include oxides of semi metals, Al2O3, ZnO etc.
Why are aluminium and zinc oxides called amphoteric oxides?
These oxides are called amphoteric because they can dissolve in acidic solutions to form metal cations in the solutions but can also dissolve in strongly alkaline aqueous solution to form oxyanions of the metals: aluminate or zincate.
Is ammonia an amphoteric substance?
No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. Sodium sulfite will only act as a base, and thus it is not amphoteric.
Is ammonia amphoteric according to bronsted lawry concept?
no amonia is not amphoteric it is simply base
What is the difference between amphoteric and neutral compounds?
difference between amphoteric solutions and neutral solutions
Is radium hydroxide amphoteric?
No, radium hydroxide is not amphoteric. An amphoteric compound is one that has characteristics of and is capable of reacting like either an acid or a base. Radium is a metal from Group 2 of the periodic table, and these Alkaline Earth metals form hydroxides that are definitely basic in nature. In general, amphoteric compounds will not be formed by metals at the end or through the middle of the periodic table, but will include poor metals or metalloids in their makeup. An example might be aluminum hydroxide. We see the poor metal aluminum forming Al(OH)3 molecules, which display characteristics of amphoterism. A link can be found below for more information.
What are the borderline elements called on the periodic table?
The "borderline" elements on the periodic table are the diagonal row of elements that separates the metals from the non-metals. They are called metalloids and the amphoteric line.
Oxides that are both acids and bases?
Such oxides are known as the amphoteric oxide they include oxides of semi metals, Al2O3, ZnO etc.
Why are aluminium and zinc oxides called amphoteric oxides?
These oxides are called amphoteric because they can dissolve in acidic solutions to form metal cations in the solutions but can also dissolve in strongly alkaline aqueous solution to form oxyanions of the metals: aluminate or zincate.
Is a bicarbonate ion an amphoteric substance?
amphoteric
Is salt amphoteric?
Sodium chloride is not amphoteric.
Is ciprofloxacin acidic basic amphoteric or neutral?
amphoteric
What is a common amphoteric substance?
Water is an amphoteric substance.
Is ammonia an amphoteric substance?
No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. Sodium sulfite will only act as a base, and thus it is not amphoteric.
Does sodium calcium are amphoteric oxides?
The oxides of sodium and calcium are not amphoteric: They are strongly basic. The most common amphoteric oxides are silica and alumina.
Is sulphate ion amphoteric?
sulphate ion is not amphoteric because according to Bronsted-Lowry concept an amphoteric specie is that which can donate as well as accept aproton but sulphate ion is not capable of donating proton so it is not amphoteric
Describe a substance which will react with both acids and alkalis to form a salt and water?
Such substances are semi-metals as Zn,Sn and Al , and their oxides, such substances are known as Amphoteric.
