Which chemical acts as both metal and non-metal?

Answer 1

Hydrogen is unique in that it's atoms have a single proton, and typically, a single electron.

When hydrogen undergoes a reaction with a metal, it will gain another electron. This makes two in its only energy level, which is therefore its valence shell as well. Hydrogen (an exception to the octet rule) is satisfied with only two electrons in its valence shell, and acts like a non-metal in this fashion.

Alternatively, hydrogen can also lose it's only electron. This happens, usually, when it reacts with a non-metal. In this case, hydrogen is acting like a metal by giving up it's electron.

Answer 2

All elements in the Metaloids group including Silicon and Germanium act as metals and non-metals which is why Silicon is used in computer chips as it can be an electrical conductor and insulator.

Answer 3

Salt, chemically known as sodium chloride. Sodium is a metal, chlorine is a non-metal. They bond ionically as the compound sodium chloride, which has completely different properties from its component elements.

Answer 4

metalloids or semi metals as Aluminium , Zinc and Tin when react with alkali form the salts similar as formed by non metals, e.g NaAlO2 , Na2ZnO2 and Na2SnO2.

Answer 5

A nonmetal is aluminum
