Start with the element that has the lowest boiling point. HeliumNeonArgon

The element with the lowest boiling point among Helium, Neon, and Argon is Helium. Here are the steps to find this:

1. Look up the boiling points of each element. The boiling point of an element is the temperature at which it changes from a liquid to a gas.

2. The boiling points for Helium, Neon, and Argon are as follows:

   • Helium: -268.93°C
   • Neon: -246.08°C
   • Argon: -185.85°C

3. Compare these values. The lower the boiling point, the quicker the element turns into a gas.

4. From the given values, we can see that Helium has the lowest boiling point. Therefore, Helium is the element that turns into a gas at the lowest temperature among the three.
