What is silver? (Apa itu perak?)

Silver is one of the chemical elements. Silver’s chemical symbol is Ag (Gold’s symbols is Au) and its atomic number is 49 (Gold’s is 79). Silver sits directly above Gold in the Periodic Table of the Elements as its electronic structure is similar. Therefore Silver has similar characteristics to Gold. Silver is relatively inert and malleable. Unlike Gold, Silver does tarnish. The best way to clean silver is with mild soap and warm water and then pat dry with a soft cloth. Chemical cleaners such as “silver polish” are completely unnecessary.

What is gold?

Gold is one of the chemical elements. Gold's chemical symbol is Au and its atomic number is 79. Its chief characteristics are that it is inert and malleable. Inert means gold does not interact with other chemicals or compounds. Gold doesn't tarnish and even the strongest acids have no effect. Thus, gold lasts forever - and stays shiny the whole time!
