Reason:
Its the only one you can spell with the atomic symbols
C-Ar-B-O-N
Ne-O-N
Si-Li-C-O-N
P-H-O-S-P-H-O-Ru-S
Xe-N-O-N
Dude, i got too much time on my hands!
The list includes hydrogen, oxygen, nitrogen, carbon, and iron.
The element iron does not belong in the list because it is a transition metal, while the other elements are nonmetals.
Hydrogen, oxygen, nitrogen, and carbon are all nonmetals and are found in the upper right corner of the periodic table. Iron, on the other hand, is a transition metal and is found in the middle of the periodic table.
Hydrogen is a colorless gas and the lightest element. Oxygen is a highly reactive gas and is essential for life. Nitrogen is a colorless and odorless gas and makes up about 78% of the Earth's atmosphere. Carbon is a versatile element that is found in all living organisms. Iron is a strong, ductile, and magnetic metal.
Hydrogen is used in the production of ammonia and in fuel cells. Oxygen is used in medical treatments, welding, and combustion. Nitrogen is used in fertilizer production and as an inert gas in packaging. Carbon is used in the production of steel and as a key component in many compounds. Iron is used in the production of steel and in various industrial applications.
