Reactivity of metals - Coggle Diagram
Reactivity of metals
metals are good conductors of heat and electricity
the most reactive metal is potassium
atomic size and reactivity of elements increases down the group
metals are ductile and malleable
metal + Oxygen = metal oxide
changing the state of water changes the rate of reaction
metal + acid = hydrogen gas + salt
sulphuric acid ----> metal sulphate
metal + nitric acid ----> metal nitrate + H2
Magnesium + steam ----> H2 + Magnesium oxide
Sodium + water ----> Sodium hydroxide + H2
group 1 (Lithium, Sodium and Potassium)
Group 1 (metals) + Water (aq) ----> metal hydroxide + H2
Reaction b/w Mg + O2: needs energy to react
(in the presence of water) Iron + O2 = Iron oxide/ Rusting/ Ferric oxide
dilute acid and concentrated acid
Magnesium+ hydrochloric acid ----> Magnesium chloride + Hydrogen gas
Magnesium+ sulphuric acid ----> Magnesium sulphate + Hydrogen gas
Magnesium+ nitric acid ----> Magnesium nitrate + Hydrogen gas
