One isotope of aluminum is 27/13al. how many electrons would a neutral atom of this isotope contain?

A neutral atom of _13^27Al contains 13 electrons.

The atomic number is 13, so the atom has 13 protons (+).

If the atom is neutral, it must contain 13 electrons (-).

Total distance, d = 19 cm

Explanation:

It is given that, A toy car is placed at 0 on a number line. It moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left.

We know that the distance travelled by a toy car is equal to the sum of total path covered. The displacement is equal to the shortest path covered by an object.

So, the total distance is given by,

d = 19 cm

Hence, this is the required solution.
