What are the most abundant elements in the world?
The question is ambiguous. It isn't clear if by "world" you mean the observable Universe, or our planet Earth. The abundance varies. For instance, in Earth's crust (i.e., the part we can easily access), the most abundant elements are oxygen, silicon, and aluminium - in that order.
What 3 elements are more abundant than carbon?
The three elements more abundant than carbon in the universe are hydrogen, helium, and oxygen. Hydrogen is the most abundant element, making up about 74% of the universe's normal matter. Helium follows, accounting for about 24%, while oxygen is the third most abundant element, constituting around 1% of the universe. Carbon, while crucial for life, is less abundant, making up only about 0.5% of the universe.
