Reactivity Of Metals Flashcards
Metal + Water -> …
Metal hydroxide + hydrogen
Sodium + Water ->…
Sodium hydroxide + Hydrogen
Are metal hydroxides acids, alkalis or neutral?
Strong alkali
What is a displacement reaction?
When a more reactive metal takes the place of a less reactive metal from its compound.
Magnesium + copper sulphate->…
Magnesium sulphate + Copper
Because magnesium is more reactive than copper
Why are group 1 elect very reactive?
There is only one electron in the outer shell so there is a weaker electrostatic force of attraction between the nucleus and the electrons so they can react more easily.
Why potassium reactive more than lithium?
As you move down the group it is a further distance between the electrons and the nucleus so there is a weaker electrostatic force of attraction and the electrons can react more easy.
