A half-life of a radioisotope is the time required for half of a sample to decay. In this case, a 50-g sample becoming 25 g after 18 days indicates that the half-life of the radioisotope is 18 days, as the sample has decreased to half its original amount in that time.
The half-life of a radioisotope is the time it takes for half of a sample to decay. In this case, a 20g sample reduces to 5g after 2 days, indicating it has gone through two half-lives (20g to 10g in the first half-life, and 10g to 5g in the second). Therefore, each half-life is 1 day. Thus, the half-life of the radioisotope is 1 day.
The half-life of a radioisotope is the time it takes for half of the substance to decay. In this case, a 20 g sample reduces to 5 g in 2 days, meaning it has undergone two half-lives (20 g to 10 g, then 10 g to 5 g). Therefore, each half-life is 2 days divided by 2, which equals 1 day. Thus, the half-life of the radioisotope is 1 day.
The half-life of the radioisotope Bismuth-210 (Bi-210) is approximately 5.01 days. This means that it takes about 5.01 days for half of a sample of Bi-210 to decay into its decay products.
The half-life of the radioisotope Ag-110 is approximately 24.6 seconds. This means that half of the radioactive atoms in a sample of Ag-110 will undergo radioactive decay in that amount of time.

Half life is the time taken for approximately half of the available nuclei in a sample of radioactive material to decay into something else. It's a characteristic of the isotope, for example, the half life of the isotope of iodine, I131 is 8.08 days. Half lives can vary from fractions of a second to thousands of years.
