How many radiations are emitted by uranium?
Uranium-238 emits alpha radiation; its half-life is 4,468×109 year.
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.
A rock originally had 1500 atoms of U-235 and it now has 750 how old is it?
For a rock to have started with 1500 atoms of any element and now have 750 it has undergone radioactive decay equal to one full half life (i.e. there are half the number of atoms now than at the beginning).Uranium-235 has a half life of 7.038×108 years.As such, the rock is 7.038×108 or 703 million years old.
