Accepted Answer

So here the practice question says fill in the gaps for the following table. So for the first column we have our symbol and this just encompasses our element symbol and its charge. This charge comes from the result of adding up all your protons and electrons. And because of that, we can call it more specifically the net charge. So here the net charges three plus now protons, we know that protons are equal to our atomic number Z. But here we don't have a column for atomic number Z. So we're gonna say instead that the protons are connected to the electrons and together they give us our net charge neutrons were gonna say neutrons here equal your mass number which is a minus Z. Which is your atomic number. But again, because we don't have atomic number as a column, we'll just say since Z equals number of protons, we're gonna say it's minus protons. Then electrons. You can also group with protons in order to determine our charge. And then mass number here. Mass number is a It comes from looking at the number of protons plus neutrons within an element or an ion. And then charge can be again determined by looking at the number of protons and electrons. So if we start out with the first one, we're gonna say here because we know the element is cobalt, we know what its atomic number will be. We just look it up on the periodic table. So seo is cobalt, it has 27 protons because its atomic number is 27. Next determining the number of neutrons. We're gonna take the mass number which is 59 and minus it by the 27 protons. And that'll give us 32 neutrons For electrons. We can stay here for electrons. Number of protons is 27. We don't know. Let's see. We don't know how many electrons we have here. So electrons will be unknown. Then. We're going to say next that our charge is plus three because here is three plus. We're going to subtract 27 here from both sides. Now that gives us -24, which makes sense because each electron is negatively charged. So that will give us 24 electrons. So again we had 20-24 but negative 24 m, there's 24 negative electrons. So yards and it would just be 24. For the next one. We know the proton number is 34. So we know the atomic number. Looking on the periodic table. That would give us selenium or S. E. As our element symbol mass number comes from adding up the protons plus the neutrons. So that will give us 80 as our mass number. Then we know the number of protons we have is plus 34 Plus our 36 electrons. That's negative 36 because each electron is negatively charged. So overall this would be 2 - or -2. So this would be selenium ion SE 2 -. Alright, next we have 76 here. Look on the periodic table that gives us Os which is osmium Alright, number of electrons would be 76 plus. The number of electrons which you don't know plus the net charge which is two plus or plus two. Subtract 76 from each side. So that would give us -70 for which really means we have 70 for negatively charged electrons. Mass number here would be 76 protons plus 116 neutrons. So that will give us 192. And then finally we have here 80 as the number of protons Look on the periodic table actually, one more thing. This would be osmium two plus. So we have 84 atomic number for the last column or last row. And that gives us hkg which is called mercury mass number would be number of protons, which is 80 plus number of neutrons, which is 1 20. So that's 200 for a mass number. And then finally, to determine the overall charge. At the end, we have 80 positive protons plus negative 78 for the 78 electrons. So that gives us overall a two plus charge. So this would be mercury two plus ion. So, this is the approach you need to take in order to find out each one of the subatomic particles net charge and mass number for each of the given ions
