Answer:
1.88 x 10^5
Explanation:
You have to round because all of the numbers in 187515.4207 are significant
Round to: 188000
Put in scientific notation:
1.88 x 10^5
If you use its electronic structure the last number should be a five so something like (2,5), (2,8,5) or (2,8,8,5) etc.
The elements therefore with 5 as it's final number and 5 on the outer orbit are N, P, As, Sb, Bi, Uup. Therefore with the answers given to you the answer is most likely 4) Phosphorus. <span />
