Use the worked example above to help you solve this problem. The half-life of the radioactive nucleus _(88)^(226)text(Ra) is 1.6 103 yr. If a sample initially contains 4.00 1016 such nuclei, determine the following:. (a) the initial activity in curies µCi
(b) the number of radium nuclei remaining after 4.4 103 yr nuclei
(c) the activity at this later time µCi

Explanation:

From the information given:

The half-life = 1.6103 years

The no. of the initial nuclei =

Using the formula:

where;

decay constant

∴

The number of radium nuclei N = 5.94 × 10¹⁵

The initial activity

Since;

1 curie = 3.7 × 10¹⁰ Bq

Then;

c) The activity at a later time is:

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
