The core of the earth contains many elements, not just two.However the two most abundant elements in the earth's core are nickle and iron (the final two elements that a star can make by fusion before it dies).But there are many other elements in the core, especially ones with atomic masses greater than that of nickel and iron. Many of these heavy elements are radioactive (e.g. radium, thorium, uranium) and it is the heat generated by the decay of these heavy radioactive elements that keeps the core hot and the outer core liquid.
Although many elements make up car batteries, the nickel and iron battery has dominated for decades.
The two elements that make up steel are iron and carbon. Other elements can also appear in the steel, but these two are the ones that cause it to be called steel.
