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?
