Alkalis are metals, specifically the IA group. So no, they won't react with metals.
Yes, sometimes: for example aluminium react with sodium hydroxide.
Copper doesn't react wih alkalis.
Some metals react with alkalis; for example the reaction of aluminium with sodium hydroxide is:2 Al + 2 NaOH + 2 H2O = 2 NaAlO2 + 3 H2
Metalloids react with both acids and alkalis.
Metals loss electrons and nonmetals gain electrons.
Au and Pt are some metals which do not react with O.
Alkalis and metals do not usually react.
Such metals are Sodium and Potassium (and all the alkali metals).
Copper doesn't react wih alkalis.
When alkalis react with ammonium salts, ammonia gas and another salt is produced
Some metals react with alkalis; for example the reaction of aluminium with sodium hydroxide is:2 Al + 2 NaOH + 2 H2O = 2 NaAlO2 + 3 H2
Such substances are semi-metals as Zn,Sn and Al , and their oxides, such substances are known as Amphoteric.
They are all group 1 elements and react with water to from the corresponding hydroxides which act as alkali (base). Hence the name.
Yes, that is called a neutralization reaction.
Yes :)
strongest bases are the hydroxides of alkali metals and alkaline metals.

Metalloids react with both acids and alkalis.
