i. What was the half-life of the new isotope?

Answer 1

Answer:

4 days.

To calculate half life divide original value by 2.

1.2 ÷ 2 = 0.6 grams

Answer 2

0.6 minutes was a half life of new isotope.

What is radioactive isotope?

A radioisotope is an unstable form of chemical element date releases radiation is it breakdowns and becomes more stable so, radioisotopes may occur in nature or it will be made in a laboratory also.

Uses of radioisotopes:

It is used in cancer treatment, food irradiation, gauges and radiography.

The time required for half of something to undergo a process such is the time required for half of the items of radioactive substance to become disintegrated.

Half life is the time taken for the radioactive of a substance to phone to half its original values where is mean life is average lifetime of all the nuclei of a particular unstable atomic species.

Radioactive element has a half life of one hour this means that half of it will decay in one hour after another hour half of the remaining material will decay.

Half life of the new isotope is 1.2/2 = 0.6 minutes

0.6 minutes was a half life of new isotope.
