Definition
- Noun:
- Inert gas: A gas that does not undergo chemical reactions under a given set of conditions. It is chemically inactive and stable.
- Noble gas: A specific group of inert gases found in Group 18 of the periodic table (e.g., helium, neon, argon).
Usage Examples
- Noun:
- Argon là một khí trơ được sử dụng trong bóng đèn. (Argon is an inert gas used in light bulbs.)
- Các khí trơ như neon tạo ra ánh sáng màu khi có dòng điện chạy qua. (Inert gases like neon produce colored light when an electric current passes through.)
- Bầu khí quyển chứa một tỷ lệ nhỏ khí trơ. (The atmosphere contains a small percentage of inert gas.)
Advanced Usage
- Scientific Context: In chemistry and engineering, "khí trơ" often refers to gases used to create non-reactive environments, such as in welding or semiconductor manufacturing.
- Môi trường khí trơ ngăn kim loại bị oxy hóa trong khi hàn. (An inert gas environment prevents metal from oxidizing during welding.)
Variants and Related Words
- Khí hiếm (n): Noble gas. This term is often used interchangeably with "khí trơ" but specifically refers to the elements in Group 18.
- Heli là một khí hiếm. (Helium is a noble gas.)
Synonyms
- Inert gas: A gas that is not chemically reactive.
- Noble gas: Any of the chemically inert gaseous elements of Group 18.
- Non-reactive gas: A gas that does not readily enter into chemical combination.
