Step-by-step explanation:
look it up on google :)
The answer is Beryllium atom has a larger radius by 2 times.
Nitrogen atom: 5.6 × 10⁻¹¹ = 5.6 × 10⁻¹⁻¹⁰ = 5.6 × 10⁻¹ × 10⁻¹⁰ = 0.56 × 10⁻¹⁰
Beryllium atom: 1.12 × 10⁻¹⁰
Since 1.12 is bigger than 0.56, then the radius of beryllium atom is larger of the radius of nitrogen atom. Let's see by how many times:
1.12 × 10⁻¹⁰ : 0.56 × 10⁻¹⁰ = 1.12 : 0.56 = 2
We can see that
there are six sides
so, n=6
so, firstly we will find total angle
total angle =(n-2)*180
total angle =(6-2)*180
total angle =720
so, sum of all angles must be 720
so, we get
now, we can solve for x

-3
</h2>
Step-by-step explanation:
chage the proper fraction to improper and then multiply
For every decimal place that you move over, add one to the exponent of the 10.
So in this problem, you would move nine spaces to the left, so the exponent above the 10 would be a nine.
Therefore, the scientific notation would be:
4.4982529 x 10^9
