Question

Table for recording data on three naturally occurring germanium isotopes, including atomic number and mass number.

Accepted Answer

Hey, everyone, we're told that potassium a mineral that supports several body functions has three naturally occurring isotopes provide the missing data for potassium 41 of the isotopes of potassium. In the following table, as we've learned atoms of the same element with different atomic masses are called isotopes. These are atoms with equal number of protons, but different number of neutrons. And they can be represented in the following way where X represents our element symbol A represents our mass number. W Z represents our atomic number. Now let's go ahead and use this information to answer our question here. We can see that A is equal to 40. So this means our mass number is 40. We also see that our atomic number is and we know that our atomic number is equivalent to the number of protons and the number of electrons. So this means we have 19 protons as well as electrons. Now let's go ahead and determine the number of neutrons. Since we have an isotope here, the number of neutrons is going to be different from the number of protons. So to calculate the number of neutrons, all we need to do is take our mass number and subtract the number of protons. So, plugging in these values, we have a mass number of 40 and we're going to subtract protons. This means we have a total of 21 neutrons. So these would be our final answers. Now, I hope this made sense and let us know if you have any questions.
