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

Answer:

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.
