Question

a red-orange solid with a melting point of 1085 °C that cannot be broken down into simpler substances by chemical processes

Answer 1

Copper is an element which has a red-orange colour and is solid at room temperature. It has a melting point of 1085 °C, and it cannot be broken into simpler substances by chemical processes. It cannot be broken down as copper is an element which is made up of only one type of atom. Atoms are the smallest particles of matter, and there is nothing further than that.
