liraira [26]3 years ago

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.

nikitadnepr [17]

Answer : The types of radiation known to be emitted by radioactive elements are, alpha particles, beta particles, or gamma rays.

Explanation :

Radioactive decay : It the process in which an unstable atomic nucleus loses energy by emitting the radiations like, alpha particles, beta particles, or gamma rays.

The naturally occurring radioactive elements are, radium, thorium, and uranium.

Alpha particle : It is also known as alpha radiation or alpha ray that consists of 2 protons and 2 neutrons that are bound together into a particle that is identical to the helium nucleus. It is produced in the process of alpha decay.

Beta particle : It is also known as beta radiation or beta ray. During the beta decay process, a high energy and speed electron or positron are emitted by the radioactive decay of atomic nucleus.

Gamma particle : It is also a gamma radiation or gamma ray that is arising from the radioactive decay of atomic nuclei. It has shortest wavelength waves and imparts high photon energy can pass through most forms of matters because they have no mass.
