## Main Question or Discussion Point

Hey I'm new to this forum, just want to say hi! I'm not sure if this is the rite place to put this but sry if i posted in the wrong section >.<

I'm actually working on an assignment in my natural science course and I'm stuck on this question cause i'm not sure how to use the variables in the equation.

The californium-242 nucleus 242/98 Cf decays via alpha decay with half life of 210s

A)what is its daughter nucleus?

B) if we originally have 10 000 californium-242 nuclei, how many will remain as californium after one half-life? Explain

C)if we originally have 10 000 californium-242 nuclei, how many will remain as californium after five half-life? Explain

Ok so how I view this... I need to use the Decay Law equation to find the daughter nucleus rite? since its going through alpha decay.

So equation would be N(t) = N e^(-λt)

N(210) = N e^(-λ210)

is N = 242?

So... wuts e? and λ?
