Arrange the given halogens in increasing order of boiling points.

Explanation

To arrange the given halogens (fluorine, chlorine, bromine, iodine, and astatine) in increasing order of boiling points, we can follow these steps:

### Step 1: Understand the Trend in the Halogen Group
The halogens are found in Group 17 of the periodic table. As we move down the group from fluorine to astatine, several factors influence the boiling points:
- **Atomic Size**: The size of the atoms increases as we move down the group.
- **Molecular Mass**: The molecular mass of the halogens increases down the group.
- **Van der Waals Forces**: The strength of Van der Waals forces (dispersion forces) increases with increased size and mass, leading to higher boiling points.
