Answer:
a single d orbital can hold 10 electrons
The amount of the original isotope that remains after 30 days is 11.14.
<h3>What is the half life?</h3>
The half life of a radioactive nuclide has to do with the time that it takes for only half of the original number of nuclides to remain.
Now;
No = 150 grams
N = ?
t1/2 = 8 days
t = 30 days
Then;
N/No = (1/2)^t/t1/2
N/150 = (1/2)^30/8
N/150 = (1/2)^3.75
N = (1/2)^3.75 * 150
N = 11.14
