What is the reason radioactive decay is measured in half-life’s instead of just using the elements “full-life”?

Is there something special about the halfway point? Does the decay happen at a steady pace or exponentially?

It’s not half the time it takes to decay, it’s the time it takes for half the substance to decay, it’s more like halving-life

the reason you can’t measure the “full life” is because it’s exponential, the more you have the faster it decays, the less, the slower, which is why it takes the same time to decay one half no matter the size you have

So you can basically keep dividing in two forever, after 2 half-lives you have 1/4 th of the original, after 3 you have 1/8 th and so on, since there’s a huge amount of atoms it’s almost impossible for them to all decay
