Iron and oxygen
A compound is 2 or more elements permanently combined. Rust is a combination of iron and oxygen, both elements- into iron oxide, a compound.
Carbon and oxygen
rust made a building collapse and 2 much rust is bad 2 our plants. and in magnetizing unsnarls and others make sure that its rust is little because if too much rust is in the iron it can't work........
including "unknown elements" there are 59 elements in half of the periodic table, not including them there is 55.5 Added: 92 natural elements/2 = 46 natural elements make up 1/2 periodic table.
A substance made up of the atoms of two or more elements is called a compound. Compounds form when different elements chemically bond together in specific ratios. The properties of compounds are different from the properties of the individual elements that make them up.
O and Fe
No elements are made up of a compound. I think you mean 'Which elements make up iron oxide?', and the answer to that is iron and oxygen.

Carbon and oxygen
Well there are 2 hydrogen atoms and 1 oxygen atom so therefore the answer is 2 different elements that make up h2o
Yes, chemical compounds are made up of elements combined together.
Hydrogen and helium.
carbon dioxide and nitrogen are 2.
Xylem may be made up of tracheids and vessel elements.

2 atoms of Hydrogen and 1 of Oxygen
