Oxidising Ability Of Halogens Flashcards
1
Q
What is meant by oxidation ability ?
A
The power to take electrons away from something else and cause something to be oxidised
2
Q
What is the oxidising ability of halogens ?
A
Oxidising ability decreases down the group 7
3
Q
Why does the oxidising ability depend on ?
A
The ability depends on the attraction between the atoms nucleus and a second atoms electrons
4
Q
So why’d eps the oxidising ability of halogens decrease ?
A
Because the atomic radius increases which causes more shielding of the nucleus an so there is a greater distance between the nucleus and extra / outer electrons so electrons are gained less easily
5
Q
Which halogen is the best oxidising agent ?
A
Fluorine
6
Q
Which halogen is the worst oxidising agent ?
A
Iodine
