The percentage of strontium-90 in the environment will never reach zero due to its long half-life of about 29 years, meaning it takes a considerable amount of time for it to decay to safe levels. Additionally, strontium-90 can be produced from ongoing nuclear reactions and accidents, which can introduce new amounts into the environment. While its concentration may decrease significantly over time, complete elimination is unlikely.

What is the number of unpaired electrons in a strontium atom?
A strontium atom has the atomic number 38, which means it has 38 electrons. The electron configuration of strontium is [Kr] 5s², indicating that its outermost shell (the 5s subshell) is fully filled with 2 electrons. Since all the electrons in strontium are paired, it has zero unpaired electrons.
What is the oxidation number of strotium in the hydride of strontium?
Well, honey, the oxidation number of strontium in the hydride of strontium is +2. It's like asking if Betty White is a national treasure - the answer is obviously yes. So, in this case, strontium is happily rocking that +2 oxidation number like a boss.
What is the 5 percent rule to find if the y-intercept is significant?
The 5 percent rule states that if a confidence interval for the y-intercept does not contain zero, then the y-intercept is considered statistically significant at the 5% level. This means that the y-intercept is unlikely to be zero in the population.
What is the charge on the strontium ion?
36 electrons are there in Sr2+ ion
explain how newton’s first law can be derived from newton’s second law?
Force = mass x acceleration; acceleration = force / mass. If force is zero, then obviously, acceleration will also be zero.
What is 0 as a decimal?
0 percent as a fracton is 0/100 so as a percent it will be 0.00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000( it will go for ever)ANSWER:The answer will always be zero.
