Answer:
The radius of a Magnesium atom is [tex](1.5).10^{-10}m[/tex]
Explanation:
The question is wrong and a graph is missing.
It should be '' A hydrogen atom has a radius of [tex](2.5).10^{-11}m[/tex] ''
I also add the missing graph.
If we take a look at the graph, we can see that using that scale the atomic radius of the Hydrogen is [tex]6mm[/tex] and the atomic radius of Magnesium is [tex]36mm[/tex]
Therefore, the radius of the Magnesium atom
[tex]\frac{36mm}{6mm}=6[/tex]
is six times bigger than the Hydrogen atom
If we multiply by 6 the radius of the Hydrogen atom ⇒
[tex](6).(2.5).10^{-11}m=(1.5).10^{-10}m[/tex]
