Explanation
Rutherfordium is a synthetic radioactive element with atomic number 104. Mendelevium has atomic number 101 and was first made in 1955, before the discovery claims for rutherfordium in the 1960s. Seaborgium and nobelium are synthetic elements, not naturally occurring constituents of uranium ores. Statements 1 and 2 are correct.
