It is 120 because first 8 goes into 96 which is 12. just add the 0 since u cant do anything else and it’s 120.
A negative exponent means the number of the exponent divide by the number. The the radius of beryllium atom is larger than the radius of a nitrogen atom by two times.
Given information-
The radius of a nitrogen atom is
meters.
The radius of a beryllium atom is
meters
<h3>Negative exponents</h3>
A negative exponent means the number of the exponent divide by the number.
As the radius of the nitrogen atom is
meters. Convert it in the power of negative exponent of 10.
Let the radius of the nitrogen is
mm. Thus,
![r=5.6\times 10^{-11}\\ r=5.6\times 10^{-10-1}\\ r=5.6\times 10^{-10}\times10^{-1}\\ r=\dfrac{5.6\times 10^{-10}}{10} \\ r=0.56\times 10^{-10}](https://tex.z-dn.net/?f=r%3D5.6%5Ctimes%2010%5E%7B-11%7D%5C%5C%0Ar%3D5.6%5Ctimes%2010%5E%7B-10-1%7D%5C%5C%0Ar%3D5.6%5Ctimes%2010%5E%7B-10%7D%5Ctimes10%5E%7B-1%7D%5C%5C%0Ar%3D%5Cdfrac%7B5.6%5Ctimes%2010%5E%7B-10%7D%7D%7B10%7D%20%5C%5C%0Ar%3D0.56%5Ctimes%2010%5E%7B-10%7D)
Now the base of the exponents of both the atoms are same. As the radius of the nitrogen atom is
meters and the radius of the beryllium atom is
. Thus the radius of beryllium atom is larger.
To calculate how many times, the radius of beryllium atom should be divided by the radius of a nitrogen atom. Thus,
![=\dfrac{1.12\times10^{-10}}{0.56\times10^{-10}} \\ =2](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1.12%5Ctimes10%5E%7B-10%7D%7D%7B0.56%5Ctimes10%5E%7B-10%7D%7D%20%5C%5C%0A%3D2)
Thus the the radius of beryllium atom is larger than the radius of a nitrogen atom by two times.
