Group 17 (halogens) Flashcards
1
Q
Define non metals
A
Acceptors of protons
Halegens are most reactive non metals
2
Q
Reactivity trend down group
A
Increases
3
Q
How reactions between halogens and other halide ions are used to establish the order of reactivity ?
A
Br2 + 2KI > i2 2kbr
Br2 + 2I- > I2 + 2BR-
4
Q
What are halogen displacement reactions
A
Redox as the halogens gain electrons and halide ions lose electrons
5
Q
Test for halide ions
A
Chloride white
Bromide cream
