Hi

1) Can all chemical elements be superconductive?

2) It is said that in diamagnetic materials there are no unpaired electrons. Does this mean that only such materials can be superconductive?

This is vague. Are you asking of a metal made of just one element can be a superconductor? Then yes. Hg, the first superconductor discovered, is made up of just one element. If you are asking if a free atomic element can become a superconductor, then that question makes no sense because an element isn't a solid and has no "conduction" properties.

Not all elements are superconductors, i think so, or at least we don't know conditions (temperature, pressure) should be for some elements such as copper , gold to become superconductors

You need to read the statements carefully. I said that elemental solids CAN be a superconductor. That statement does NOT imply that ALL elements are superconductors!
