Answer:
Radium and Polonium
Explanation:
Marie Curie won the 1911 Nobel Prize in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes.
If a substance is very stable it will take a lot to break it down. If it's unstable it will break down very easy and fast.
They attach to a certain substrate and weaken the inter-molecular forces within the substrate. This weakens the bonds, allowing the reaction <span>to occur much faster.</span>
Since 569324 mL = 569.324 L which is much more than 1.33 L that means it cannot be diluted to a volume of 1.33 L, so this must be 569.324 mL.
This question is solved by using the dilution equation which is : 
Where 
= Initial concentration
= Initial volume
= Final concentration
= Final volume
In our question , the given information is : V1 = 569.324 mL
M2 = 4.87 M and V2 = 1.33 L and we need to find .
When we use dilution equation we need to make sure that both the units of volume have same units.
is in 'mL' and is in 'L' , so we will first convert into 'L'
= 
= 0.569324 L
Now we will plug in the values of 
, in dilution equation and will calculate the value of .
(Initial concentration) = 11.38 M
