Choose the correct answers

Answer 1

Here are the matches for each element with its correct group:

- Cerium (Ce) **__________**: Lanthanoids (Lanthanide Series)

- Astatine (At) **__________**: Halogens

- Radon (Rn) **__________**: Noble Gases

- Magnesium (Mg) **__________**: Alkaline Earth Metals

- Thorium (Th) **__________**: Actinoids (Actinide Series)

- Lithium (Li) **__________**: Alkali Metals

- Manganese (Mn) **__________**: Transition Metals

So, the completed matches are:

- Cerium (Ce) - Lanthanoids (Lanthanide Series)

- Astatine (At) - Halogens

- Radon (Rn) - Noble Gases

- Magnesium (Mg) - Alkaline Earth Metals

- Thorium (Th) - Actinoids (Actinide Series)

- Lithium (Li) - Alkali Metals

- Manganese (Mn) - Transition Metals
