Respuesta :

half-life is basically how long it takes for a radioactive molecule to get to 1/2 of its original mass.

so if sodium 24 mass was 5g and it's half life was 24years then:

after every 24years 1/2 of 5g would have decayed. so in 48years there will only be 2.5g left.

The half life of sodium -24 is 15 hour.

What is half life?

The duration needed for an amount to decrease to half its original is known as the half-life.

What is sodium-24?

Sodium is a kind of element which has atomic number 11. It has three isotopes.

The radioactive isotope sodium-24, which is employed in blood tests in medicine, degrades through beta decay as well as seems to have an of 15.0 hours.

Therefore, the half life of sodium -24 is 15 hour.
