Which nuclide has the greatest relative binding energy?   Question 14 options:   1H   59Co   238U

A rock contains 0.684 mg of 20°Pb for every 1.000 mg of 238U present. Assuming that no lead was originally present, that all the 20°PPB formed over the years has remained in the rock, and that the number of nuclides in intermediate stages of decay between 238U and 200Pb is negligible, calculate the age of the rock. (For 238U, t,2 = 4.5x10° years.) yr

a) Mrs. Price's son, Liam is currently working as a boilermaker at the Darlington Nuclear Power plant. He is working with Uranium-237 which has a half-life of 13.75 days. What mass of an initial sample of 567.5g of uranium-237 would remain after 56 days? b) Write the complete reaction for the decay of Po-210 if it undergoes 2 consecutive alpha decay followed by a beta decay followed by another alpha decay.

Answers please, preferably with an explanation

For both unstable nuclide predict the decay pathway and write the nuclear equation  1) C-11----> 2) Ac-224--->

What is the radioactivity of a 8.37-g sample of radium-223? Remember, the half-life of radium-223 is 11.4 days.

The following isotopes are all stable : 20Ne, Ne, 22Ne 10+ 10- While the following is not, so what be its decay likely? 23 Ne 10- Alpha Positron Electron capture Beta

Question 12- The half-life of Fa-282 is 6.0 hours. If a sample of Fa-282 has an original activity of 192 mCi, what is the radioactivity of the sample of Qu-280 after 1 day? (Please show all of your work so I can understand going forward, also please look at the attcahed images for a special periodic table that you may need to use to help solve the question.)

Please send me the question in 20 minutes it's very urgent plz

If a patient was administered 0.500g of Fluorine-18, what mass of Fluorine-18 remains radioactive 4.0 hours after it was administered? (if you get a fraction of half lives, just round to whole number)
