As we go down…
Boiling + melting point increases
Sonorous
When you hit an object and it make a noise
Displacement reactions
A more reactive element can take place of a least reactive element
Rust
It can occur when a metal reacts with oxygen.
Reactive series
It lists the metals in order of how vigorously they react. The top reacts most, bottom reacts the least or no reactions at all
(I)
(aq)
(I) for the liquid state
(aq) for the substance dissolved in water.
What products react with calcium and water
Hydrogen gas
What reacts with steam
Zinc + iron
Gold is..
Un reactive - it does not react with oxygen. It is often used as connections in audio equipment
