who was the first person to come up with atoms? (he called them atomos)

Explanation:

Step1: Recall scientific - notation form

Scientific notation is $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Step2: Move the decimal point

For the number $0.000098$, move the decimal point 5 places to the right to get $a = 9.8$. Since we moved the decimal point to the right, $n=- 5$. So, $0.000098 = 9.8\times10^{-5}$.

Answer:

$9.8\times10^{-5}$
