The Halogens

Question 1

Colour and states🦴

Answer 1

Pale yellow gas😀
Pale green gas🤢
Orange-brown liquid🥵
Dark grey solid👽

Question 2

Physical properties💪🏽

Answer 2

Poisonous non metals⚠️

Colored and strong smelling vapours🍃

Question 3

What increases when you go down the group?🌚

Answer 3

The melting point🔥

Question 4

Why does the melting point increase?

Answer 4

The molecules get a stronger bond so you need more energy to break them🌻

Question 5

What do the halogens exist as?

Answer 5

Diatomic molecules🐲

Question 6

Reactions of halogens

Answer 6

The halogens are reactive non-metals, becoming less reactive going down the group☄️🌈

Question 7

Reactions with hydrogen

Answer 7

The halogens react with hydrogen to form the hyfrogen halide. The reaction happens less readily going down the group🌷💐

Question 8

Metal + hydrogen —> ?

Answer 8

Hydrogen chloride/sulphate/etc

Question 9

What does fluorine do when it reacts with hydrogen?

Answer 9

Explodes, even in the dark💥🌌

Question 10

What does iodine do when it reacts with halogen?

Answer 10

It reacts very slowly if heated to 300 C ⛩with a platinum catalyst⛩, setting up an equilibrium⛩

Question 11

Trend in reactivity in non-metals

Answer 11

Non-metals get less reactive going down the group (opposite to the trend of metals)👉👈
