Video TranscriptIn this case, we're looking for something with 28 protons. So we are looking at nickel. Okay, so we've identified the symbol for this is and I the atomic mass is going to be a number of protons plus Number of neutrons in this case 28 plus. 31 makes 59. How many electrons does this thing have? Well, if we've got 28 plus is we're gonna need 28- is in order for this thing to cancel out. So we'll need 28 electrons. We can have charges but we weren't told anything about a charge. So we assume it's neutral. So for the overall simple, we're gonna get nickel 28 And then its mass is 59. So designating the specific isotope. Alright, for the next one, we've got 15 electrons. So again, nothing about having a charge. So we're gonna assume 15 protons. So we are looking at phosphorus, Okay, what's the atomic mass for this element? Well, that's given to us right here. 31. And what is the atomic number for this element? Well, that's gonna be the number of protons we've got. So 15 protons is our is our number. So this is going to be P 15. for our overall symbol for the next one. We're asked to look at Which one is the most abundant. We look at strontium, we see the thing weighs about 88. So really we're just going to look for the thing that what looks the closest to 88. So strontium 88 should weigh about 88. And since our isotopic averages 88 or 87.6, That's pretty close to 88. So we can assume that most of it is strontium 88. For the final thing we're looking for, which are isotopes. Isotopes means that they are the same element. So if you have carbon, for instance, You have carbon 12 and carbon 13, they're both carbon because they have six protons, they just happen to way different things. So in this case we've got Argon 37 Argon 40. Those are isotopes because they are both the same element. They just weigh different amounts.

IsotopesIsotope If it has 28 protons, then it is nickel. The isotopic symbol is 59Ni (one could also add the atomic number {28} as a subscript directly below the mass number {59}) Added: 59Ni is a not naturally occurring radio isotope with a half-life of 76,000 years. It is rather rare.  Add your answer:Q: What is the symbol for an element with 28 protons and 31 neutrons? Write your answer... Still have questions?
