1Which of the following elements is a halogen?
- Aiodine
- Bsodium
- Ccarbon
- Diron
2Select all elements that are group 1 metals
- Ahydrogen
- Blithium
- Csodium
- Dpotassium
- Eindium
- Fgallium
- Ghelium
3Group 1 of the periodic table are commonly known as [blank_start]Alkali Metals[blank_end]. They are found in the first column of the periodic table because they only have [blank_start]one[blank_end] electron on their outer-shell. They are soft, and have generally [blank_start]low[blank_end] melting points (for metals).

4chlorine + hydrogen → [blank_start]hydrogen chloride[blank_end]
bromine + sodium → [blank_start]sodium bromide[blank_end]
potassium + water → [blank_start]potassium hydroxide[blank_end] + hydrogen- Ahydrogen chloride
- Bsodium bromide
- Cpotassium hydroxide
5[blank_start]Alkali metals[blank_end] become more reactive, the larger the atom. This means the [blank_start]metals[blank_end] near the top of the group (lithium, sodium etc) are much [blank_start]less[blank_end] reactive than those near the bottom of the group (rubidium, caesium etc). This is because the outer negative electron is [blank_start]further away[blank_end] from the positive nucleus, meaning it [blank_start]doesn't feel as much[blank_end] attractive force and so can be more easily lost.

6At room temperature:
Chlorine is a pale green [blank_start]gas[blank_end]
Bromine is a [blank_start]brown[blank_end] liquid
Iodine is a purple-black [blank_start]solid[blank_end]- Agas
