GCSE Chemistry - Halogens and Noble Gases #12

The video covers Group 7 elements (halogens) and Group 0 elements (noble gases). It details the properties, reactivity, and trends of halogens, including their dangerous nature and ability to form diatomic molecules and covalent bonds. The video also explains how halogens form ionic bonds with metals and participate in displacement reactions. Noble gases are described as inert, non-flammable, and existing as single atoms, with increasing boiling points down the group.

Which of the following halogens is a dark grey solid that can form purple vapours?

• Iodine

• Bromine

• Chlorine

• Fluorine

As you move down Group 7, what happens to the reactivity of halogens?

• It fluctuates

• It remains the same

• It decreases

• It increases

What is the term used for a halogen ion with a 1 minus charge?

• Halogenide

• Halide

• Halate

• Halogen

In a displacement reaction, which halogen would displace bromine from a compound?

• Astatine

• Chlorine

• Iodine

• Neon

What is a key characteristic of noble gases that makes them non-reactive?

• They have full outer electron shells

• They are all liquids

• They are all metals

• They are highly electronegative
