Answer: Start by writing down the problem in your own words using as much detail as possible. Be as specific as possible in your description.
Explanation:
A neutral atom has a charge of zero which means that the number of protons or the positive charges is equal to the number of electrons or the negative charges. In this case, if the charge is zero, this should mean that the number of electrons is 2 less than the number of protons present in the atom.
Distance and displacement are hardly ever equal.
Remember that 'displacement' is the straight-line distance between
the start-point and the end-point, regardless of what path you followed
on the way.
So they're equal ONLY when the trip from start to finish was completely
in a straight line.
