Answer:
Rn-224 --> Fr-224 + beta
Explanation:
Hi
When an isotope of radon 224 undergoes a radioactive decay by emitting a beta particle, an isotope of francium 224 is obtained.
Remember that the first letter of a chemical symbol is written with a capital letter
.

Answer:
What is the following?
Explanation:
I think I can answer this, I recognize the question
Answer is: <span>edge of the length of the box measured is 1280,57 kilometers.
</span>V(raindrop) = 3,48 cm³.
V(cubic box) = 3,48 cm³ · 6,023·10²³.
V(cubic box) = 2,1·10²⁴ cm³.
V(cubic box) = 2,1·10²⁴ cm³ ÷ 10¹⁵.
V(cubic box) = 2,1·10⁹ km³.
r(cubic box) = ∛2,1·10⁹ km³.
r(cubic box) = 1280,57 km.
