<u>Given:</u>

<u>To determine:</u>
The scientific notation corresponding to the given number
<u>Explanation:</u>
Scientific notation is a concise way of representing a very large or small number. It is written in two parts:
Given Number = Digits * Power of 10
In this case we have:
0.000008 = 8.0 * 10⁻⁶
<span>We know that protons gives positive charge, neutrons no charge and electrons negative, then +14 - 12 = +2
So the charge of the atom is sign positive and magnitude 2</span>
