Answer 2

Answer:

The radius of a Magnesium atom is $(1.5).10^{-10}m$

Explanation:

The question is wrong and a graph is missing.

It should be '' A hydrogen atom has a radius of $(2.5).10^{-11}m$ ''

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 $6mm$ and the atomic radius of Magnesium is $36mm$

Therefore, the radius of the Magnesium atom

$\frac{36mm}{6mm}=6$

is six times bigger than the Hydrogen atom

If we multiply by 6 the radius of the Hydrogen atom ⇒

$(6).(2.5).10^{-11}m=(1.5).10^{-10}m$
