Question

A radioactive isotope has a rate of decay of 84%. that is, every day,

Answer 1

The half life of the radioactive isotope to the nearest tenth is  0.83 days.

What is rate of radioactive decay?

The rate of radioactive decay is the rate at which a radioactive isotope is disintegrated. The half life is the time taken for half of the original amount of radioactive isotope to remain.

Given that;

t/12 = 0.693/k

Where;

t1/2 - half life

k =decay constant

t/12 = 0.693/0.84

t/12 = 0.83 days
