Reactivity Series Flashcards
What will happen to elements that are most reactive?
they have a high tendency to lose electrons
What will happen to elements that are least reactive?
they have a low tendency to lose electrons
How to remember the elements in the reactivity series?
Please Stop Catching More Zebras I Like Hot Cute Short Giraffes (K, Na, Ca, Mg, Zn, Fe, Pb, H, Cu, Ag, Au)
Which elements react with cold water?
Potassium, Sodium, Calcium, Magnesium
Which metals can react with steam?
Metals above lead (iron to potassium)
What are the unreactive metals?
Copper, Silver, Gold
Which metals can react with acids?
metals above hydrogen
What is displacement of metals?
When a more reactive metal displaces a less reactive metal from its salt solution
How can group 1 and group 2 metals be extracted?
they can be extracted from their oxides by electrolysis as they are very reactive
How can less reactive metals be extracted from their oxides?
They can be extracted from their oxides by reduction with carbon and heat.
How can unreactive metals (gold, platinum) be extracted?
They need not be extracted as they are usually found uncombined; exists as elements
What will happen to metals in the presence of water and oxygen?
They will corrode/rust
Why do many reactive metals react with oxygen in the air?
To form stable metal oxides with strong bonds. The more reactive a metal is, the harder it is to extract the metal from its oxide.
What speeds up rusting?
The presence of sodium chloride
What are some preventive measures for rusting?
Paint, oil, plastic coating
