Argon vs. Oxygen: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on December 16, 2023
Argon is an inert, colorless, odorless noble gas, while oxygen is a reactive gas essential for combustion and respiration.

Key Differences

Argon is a noble gas with atomic number 18, known for its chemical inertness. Oxygen, with atomic number 8, is a highly reactive element, crucial for supporting life and combustion processes.

Argon, constituting about 0.93% of the Earth's atmosphere, is used in welding and lighting due to its non-reactive nature. Oxygen, making up approximately 21% of the atmosphere, is vital for breathing in animals and humans.

Argon is often used to create an inert atmosphere for scientific experiments and preservation, while oxygen is used in medical applications, metal cutting, and as an oxidizer in rocket fuel.

Argon, being heavier than air, tends to accumulate at the bottom in enclosed spaces, posing an asphyxiation risk in large concentrations. Oxygen, although essential for life, can be dangerous in excessive amounts, leading to oxidative stress or fire hazards.

In the periodic table, argon belongs to the noble gases group, known for their full valence electron shells and low reactivity. Oxygen, part of the chalcogen group, is known for its ability to form compounds with almost all other elements.

Oxygen

A nonmetallic element constituting 21 percent of the atmosphere by volume that occurs as a diatomic gas, O2, and in many compounds such as water and silica, and in iron ore. It combines with most elements, is essential for plant and animal respiration, and is required for nearly all combustion. Ozone, O3, is an allotrope of this element. Atomic number 8; atomic weight 15.9994; melting point -218.79°C; boiling point -182.9°C; gas density at 0°C 1.429 grams per liter; valence 2. See Periodic Table.
