…half-life of 8 seconds to 257Lr. The Russians proposed the name "rutherfordium" for the new element in 1967; this name was later proposed by Berkeley for element 104. Further experiments in 1969 at Dubna, and in 1970 at Berkeley, demonstrated an actinide chemistry for the new element; so by 1970 it was known that…
Element 104 was eventually named after Ernest Rutherford
