Ionic bonding Flashcards
Describe the reaction of Sodium
(alkali metals)
Reacts with O₂ - turns dull quickly
Reacts with H₂O - fizzes, and moves around quickly
Describe the reaction of Magnesium
Reacts with O₂ - bright white light, white powder formed
Reacts with H₂O - slow reaction
Describe the reaction of Aluminium
(transition metals)
Reacts with pure O₂ - new solid slowly formed
Describe the reaction of Silicon
Reacts with pure O₂ when heated with a Mg fuse
Describe the reaction of Phosphorous
Reacts with air (not pure O₂) when heated - yellow flame
Describe the reaction of Chlorine
(halogens)
Reacts with sodium when warm - bright yellow flame, white solid formed
Describe the reaction of Argon
(noble gases)
Unreactive
Describe the reactivity of Sodium
more reactive than magnesium
Describe the reactivity of Magnesium
Faster reaction when heated
Describe the reactivity of Aluminium
Less reactive than magnesium
(pure oxygen used to encourage reaction to speed up)
Describe the reactivity of Silicon
Less reactive than magnesium
Describe the reactivity of Phosphorous
More reactive than silicon
Describe the reactivity of Chlorine
More reactive than sulphur and phosphorous
Describe the reactivity of Argon
All noble gases are unreactive
What is an ion?
A charged particle (gained or lost electrons) containing a different number of protons and electrons
What is an atom?
a neutral particle containing an equal number of protons and electrons
