alkali metals react violently in cold water
It will react vigourisly
The general reaction is:2 Me + 2 H2O = 2 MeOH + H2where Me is an alkali metal.Very probable francium react violent with water.
Alkali metals, for example: 2Me + 2H2O = 2MeOH + H2 Me is the metal
When alkali metals react with cold water, they produce hydrogen gas and form metal hydroxides. The reaction is usually more vigorous for the heavier alkali metals like sodium and potassium compared to lighter ones like lithium. Additionally, alkali metals can also form alkaline solutions in water due to the formation of hydroxides.
All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).
The Alkali metals (group 1) and the Alkali Earth metals (group 2) react violently with water. Lithium and magnesium show slow reactions in boiling water. Sodium and potassium reacts violently with flames with cool water. The elements in higher periods (strontium, barium etc.) react explosively.Elements in the 1st group react rapidly with cold water. The rate of reaction increases down the period. The elements in the 2nd group also reacts with hot water or steam.
The reactivity of francium with water would be more reactive than most of the other alkali metals, because the lower down the column of alkali metals you go in the periodic table the more reactive the element becomes in cold water. Therefore, if francium was to react with cold water it would react by giving off an explosion.
Gold does not react with water or steam. i wouldn't totally agree with the above statment. There are 5 metals which don't not just 1...these are: .lead .copper .mercury .silver .gold
zinc is famous for reacting with hydrochloric acid but so will magnesium, aluminum, iron and all the alkali, alkaline earths and also group III metals.
Hot water. Metals become more malleable at greater temperatures.
Metals like copper, silver, and gold do not react with cold water because they are less reactive. This is due to their position in the reactivity series, where they do not displace hydrogen from water.
I'm not sure what the temperature has to do with it, but : alkali metal + water --> salt + hydrogen e.g. lithium + water --> lithium hydroxide and hydrogen Hope this helps! xxx
