Group 17 (halogens)

Question 1

Define non metals

Answer 1

Acceptors of protons

Halegens are most reactive non metals

Question 2

Reactivity trend down group

Answer 2

Increases

Question 3

How reactions between halogens and other halide ions are used to establish the order of reactivity ?

Answer 3

Br2 + 2KI > i2 2kbr

Br2 + 2I- > I2 + 2BR-

Question 4

What are halogen displacement reactions

Answer 4

Redox as the halogens gain electrons and halide ions lose electrons

Question 5
