Answer 1

Answer:50% of its starting atomic mass

Step-by-step explanation:

The radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. The half life is the time taken for the activity of a given amount of a radioactive substance to decay to half of its starting mass.

Answer 2

is the same

Step-by-step explanation:

Half life is define as the time it take for fifty percentage of a radioactive material to disintegrate. After the first half-life passes, half (fifty percentage) of the remaining radioactive material will disintegrate in the next half-life. Then, half of that amount in turn disintegrate in the following half-life and the halving continues.
