hydrogen.
I wouldn't always trust websites like this though, cause its just people writing answers, that we don't even know is right!
Metals of the 1st group form hydroxides by reacting with water. When metal anions react with other hydroxides, metal hydroxides are formed. Silver hydroxide is unstable.
Depending on the specific hydroxide; for example, hydroxides of the alkali metals are very caustic and dangerous.
a) SO2 acidic b) Na2O basic c) CO2 acidic d) CaO basic e) no correct answer -wrong
Metal hydroxides dissolved in water form basic solutions, with a pH greater than 7.
Hydrogen gas and metal cations

when metals react with water they form hydroxides
False. Corrosion is a chemical property. When a metal corrodes, it reacts with its environment to produce oxides, hydroxides, and other types of corrosion.
Most metal oxides and hydroxides especially those of the alkali metals and alkaline earth metals.

strong bases
strong bases
The alkali metals and the alkaline earths. These include sodium, potassium, rubidium, calcium etc.
alkali metal + oxygen --> metal oxide metal oxide + water--> metal hydroxide metal hydroxides are strong alkalis, corrosive pH=14

The hydroxide of Lithium is most soluble but all the hydroxides of alkali metals are completely soluble in water.
Hydrogen Gas I'm going to guess hydrogen gas because your hydroxide is OH and water is H2O, so you would be left with an extra single H. I had this same question on a chemistry exam and this was one of the 4 multiple choice answers he gave. The answers were oxygen, hydrogen, metal hydroxides <(definitely not this one)<, and hydrochloric acid.
