Question

What is the sum of the numbers of neutrons and electrons in the ion 208Po Enter the value in the box as a whole number.

Answer 1

Step-by-step explanation:

Hello,

Polonium has the atomic number 83, thus, it has 83 protons and electrons; in such a way, the amount of neutrons is given by the subtraction:

`neutrons=atomic.mass - atomic.number\\neutrons=208-83\\neutrons=125`

Now, the addition between the neutrons and electrons is the same atomic mass considering the previous formula, thus:

`electrons+neutrons=83+125=208`

So this procedure could be avoided by just looking at the given information "208Po" which contains the result.

Best regards.
