Do alkali metals generally make anions or cations?
Cations.
Is ammonium hydroxide an alkali?
yes
Alkali react with ammonium salt?
I give an example for ammonium salt ....hmm.... lets just take ammonium chloride as an example . How about alkali ? I take calcium hydroxide as an example for alkali . Calcium hydroxide is formed when calcium oxide reacts with water whereas ammonium chloride is formed when hydrochloric acid reacts with ammonia solution . Calcium hydroxide (alkali) + ammonium chloride (ammonium salt) --> calcium chloride + carbon dioxide + water .
What ion charges do the alkali metals form?
Alkali metals forn cations with the chrage +1.
Is ammonium hydroxide an akali or an acid?
Ammonium hydroxide is an alkali because it gives OH- ions in water and gives a salt on reaction with an acid.
What is the gas formed when ammonium salt is heated with an alkali?
carbon
Is ammonium chloride acid or alkali?

What are the alkali metal cations?
Li+ , Na+ , K+ , Rb+ , Cs+ , Fr+
What are metals that lose electrons easily called?
Alkali and alkaline earth metals. Cations.
What is ammonium?
Ammonium is the univalent NH4+ cation derived by the protonation of ammonia.
How do sizes of atoms of alkali metals compared to their positive ions?
The atomic radius of cations is lower.
What group of elements forms 1 cations?
Alkali metals, Li Na K etc
