The goal of the problem is to fill in the blank spaces in the following table. Let's first start with the first call. Since the number of protons and electrons is equal. That would mean the net charge would have to be zero, because protons are positive particles and electrons are negative particles, while neutrons aren't neutral or zero. So when you add protons and electrons together, you would get the net charge in this case would be here. So now let's look for up in Tomic. Number of five. You would get the element boron to know we have the information we need to fill in the symbol. We know that boron is be. And since the number of protons is five, the bottom number or atomic number would be five, and the mass number would be 11 because mass number is number of protons plus number of neutrons. Okay, let's move on to the next column. We can see in the symbol that this is an ion with the net charge of plus two. Given the two plus, it's the net charge for this lioness plus two. Next, looking at the bottom number or mass number, we can note that the number of protons is 26. To find the number of neutrons you subtract the top number or mass number, minus the number of protons. So 54 minus 26 would equal 28 nutrients. Since the net charge is plus two, we know that we have to less electrons than protons. So 26 minus two would be 24 electrons For this next problem. To find the number of protons have to take a look at the number of electrons and the net charge. Since we have that the number of electrons is 18 and the Net charges negative three. We know that the number of protons would have to be three less than the number of electrons, which would give us a proton number of 15 protons. Now let's take it the element With 15 protons, we get phosphorus. So now let's put that for a symbol. We have p three minus given that charge of three minus, and since we have 15 protons, the bottom number would be 15 and the top number would be 31 because 15 plus 16 are mass. Number would be 31 for the next column since the number of protons and electrons are equal. Once again, we have a net charge of zero because it would be neutral. The element with atomic number 79 would be a you or gold, and we could put this into our tape. So a you since its neutral, it wouldn't have a charge. You would just write it as a you and the number of protons or atomic number is 79. The mass number would be 79 plus 117 protons was neutrons, so the top number would be 196. For this last Colin, you could see that the net charge zero, which would mean the number of protons and electrons would be 86 because there would be equal. Now, let's take a look at the atomic number 86. The element would be are. And since it has a net charge of zero, you would just simply be RN the number of protons or atomic numbers. 86 which would be the bottom number on the top number would be protons, neutrons 86 plus 1 36 to get 222
