According reactivity towards water how many types of metals are there give example and write the reaction of them with water
Answers
Answer:
The reactivity series of metals
When metals react with other substances, the metal atoms lose electrons to form positive ions.
The reactivity series of metals is a chart showing metals in order of decreasing reactivity. In general, the more reactive a metal is:
the more vigorous its reactions are
the more easily it loses electrons in reactions to form positive ions (cations)
The table summarises some reactions of metals in the reactivity series. Hydrogen and carbon are shown for comparison.
List of metals with the reaction with cold water, reaction with dilute acids and reactivity.
Reactions of metals with water
When a metal reacts with water, a metal hydroxide and hydrogen are formed. For example, sodium reacts rapidly with cold water:
Sodium + water → sodium hydroxide + hydrogen
2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
In general, the more reactive the metal, the more rapid the reaction is.
