Video transcript

Hey, everyone were asked how many neutrons and protons are in amorous. She um to 43. If we look at our periodic table, we find that our atomic number is going to be 95. And as we know, our atomic number also represents the number of protons we have. So we have a total of 95 protons. Now to calculate the number of neutrons We can go ahead and take our mass number of 243 and subtract our number of protons, which is 95. This will get us to a total of 148 and this is going to be our final answers. So I hope this made sense and let us know if you have any questions.
