Question

The numbers represent the radius, in meters of different elementsOrder the numbers from greatest to least with greatest at the top and least at the bottom

Answer 1

Answer:

the order is

$2\times 10^{-10}\\\\1\times 10^{-10}\\\\8\times 10^{-11}\\\\7\times 10^{-11}$

Step-by-step explanation:

The numbers are

$1\times 10^{-10}\\\\2\times 10^{-10}\\\\7\times 10^{-11}\\\\8\times 10^{-11}$

The number if greater is it has less negative exponents than others.

The deceasing order is

$2\times 10^{-10}\\\\1\times 10^{-10}\\\\8\times 10^{-11}\\\\7\times 10^{-11}$
