Answer:
C. It does not participate in a decay series.
Explanation:
From this statement, we can deduce that a radioisotope that forms a stable isotope after it undergoes radioactive decay suggests that it does not participate in a decay series.
- It could have emitted any form of radioactive particles which can be alpha or beta.
- We do not know if it has a long or short half life because the value is not given.
- But since the radioactive decay in one step produces a stable isotope, we can conclude that it did not participate in a decay series.
- A decay series involves a radioactive decay in multiple steps.
Usually, the group number of the element would tell you the amount of valence electrons. In an element, their needs to be a full octet in order for it to be stable (aka happy element). Octet means 8 valence electrons in its orbital.
The theoretical yield of a reaction is 28% if 25.0 grams of product were actually produced from a reaction that has a 88% yield .
The theoretical yield of a reaction is calculated in following steps .
Identify the limiting reagent, which is the reagent with the fewest moles.
Divide the fewest number of reagent moles by the stoichiometry of the product.
Multiply the result of Step 3 by the molecular weight of the desired product.
theoretical yield : the maximum amount of product that can be produced from a given amount of reactant. this quantity of product is rarely produced during a chemical reaction. limiting reactant.
