What element has the atomic number 77?
Well, I couldn't get any stable element with mass number of 77. However the closest ones are arsenic with mass number 75 or selenium with mass number 79. Note: All the following elements listed below have isotopes with mass number 77, but are unstable with half life ranging from a few hours to nano seconds: Nickel, Copper, Zinc, Galium, Germanium, Arsenic, Selenium, Bromine, Krypton, Rubidium, Strontium and Yttrium. If you had meant atomic number, then iridium has the atomic number of 77.
