How it's used
Hydrogen is primarily used in scientific or industrial contexts in Hong Kong. While it is a standard chemical term, you will rarely hear it in casual daily conversation unless discussing science experiments or specific fuel technologies. It is pronounced with a distinct scientific register, so avoid using it in non-technical settings to prevent sounding overly formal or academic.
Examples
What is inside the hydrogen balloon is hydrogen gas.

Common mistake
Learners often confuse 氫氣 with 氦氣, which is helium. Remember that 氫氣 is highly flammable and used in fuel, whereas 氦氣 is inert and commonly used to fill party balloons because it is safer.
