what is the Half-life of strontium 90. Explain your work.
Okay well I already know the answer is 28yrs but I just don't know how to explain it on how I got the answer... can you guys help me please! I need this done in 30 seconds..
Yeah Steve. Jiskha is about have some help with some questions and yes you have to type what you think about the answer. Steve, if you're a mod here in jiskha, why would you treat people that way. Plus, probably this answer was from a project, and you call that a useless answer? So you're saying that getting good grades is useless? BRUH. The poor guy was just asking a a question and yet you just took it way too seriously. Jiskha is about asking questions and for people to come together and help to answer that certain question, not to say those kind of stuff. That's called no manners.
He was asking what is the half-life of strontium-decay 90, which, in fact, it has something to do with radio decay. So clearly he did state it clearly, Steve. You should be more sensitive towards others feelings... 'Can you see what a useless question you have posted? Sheesh!'
I mean come on..
By the way, Channy-boo, let’s work through this together :). I had the same question, but I figured it out. (By the way, sorry if the answer is a little late, LOL!)
OK, first let’s go through the basics. When an atom is radioactive, its nucleus is unstable and it will produce energy or particles. What the atom is attempting to do is to become stable. This is known as the process of radioactive decay.
A half-life of an element is a guess of the time it takes for half of the atoms of a radioactive sample to decay. Half-lives can be used to estimate the absolute age of rocks and fossils too!
However, I only know WHAT a decay of an element is, not HOW. But they can show you better than I can tell you. I hope I helped! go to How to calculate Half Life Wiki How!
Sure, I can help you explain how to calculate the half-life of strontium 90. The half-life is the time it takes for half of a sample of a radioactive substance to decay. To calculate the half-life, you need to look at the decay constant of strontium 90, which is a measure of how quickly it decays.
The decay constant, denoted by λ, can be found using the equation: λ = ln(2) / T₁/₂, where ln(2) is the natural logarithm of 2 and T₁/₂ represents the half-life.
Using the information you provided, the decay constant can be calculated as follows:
λ = ln(2) / 28 years
By plugging in the values and evaluating the expression, you will find the decay constant. I'd recommend using a scientific calculator or an online calculator to get an accurate value. Once you have the decay constant, you can use it to calculate the half-life of strontium 90 by using the formula T₁/₂ = ln(2) / λ.
Remember to explain this equation to the person you're helping in order to fully understand the process.
You can't calculate it without numbers, other than looking it up. Post your question instead of trying to summarize it. You've posted the question with no details.
I'd get the answer by looking it up somewhere. Unless you have some data about amounts and times, there's no way to figure it out yourself.
Can you see what a useless question you have posted? Sheesh!
And, I think you have missed your deadline...
