Chemistry of calcium Calcium is generally more reactive than magnesium
No, it is less reactive.
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
Yes.
No, copper is less reactive than aluminum.
Aluminum is less reactive than lithium. Aluminum forms a protective oxide layer on its surface that prevents further reaction, while lithium is highly reactive and can react violently with water or air.
No.Mg is less reactive than aluminum,therefore mg solution will not react with aluminum metal.
Aluminum is much less reactive than calcium and does not react to any significant degree with air or water. Calcium is very reactive. It reacts vigorously with water, rapidly producing hydrogen gas and calcium hydroxide and is itself flammable. Additionally, its high reactivity makes it difficult to extract from its compounds.
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
Aluminum will not react with zinc nitrate because aluminum is less reactive than zinc. In a chemical reaction, more reactive elements displace less reactive elements from their compounds. Since aluminum is less reactive than zinc, it will not displace zinc from zinc nitrate to form a new compound.
The reactivity series from highest to lowest reactivity is: potassium, sodium, calcium, magnesium, aluminum, zinc, iron, lead, copper, silver, gold. In this series, copper is less reactive than calcium, sodium, potassium, and lithium. Copper will not displace these metals from their compounds in solution (e.g., copper will not displace calcium from calcium chloride).
Iron would not react with aluminum nitrate because iron is less reactive than aluminum and would not displace aluminum from its compound.
Radium is the least reactive among calcium, magnesium, strontium, and barium. Radium is a highly radioactive metal that readily reacts with other elements, but it is less reactive compared to the other listed elements.
