what are unreactive and reactive metals? in which state they are found in nature
Answers
Answer:
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions.
A reactivity series of metals could include any elements. For example:
A list of elements from most reactive to least reactive: potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, copper, silver and gold.
A good way to remember the order of a reactivity series of metals is to use the first letter of each one to make up a silly sentence. For example: People Say Little Children Make A Zebra Ill Constantly Sniffing Giraffes.
Observations of the way that these elements react with water, acids and steam enable us to put them into this series.
