 Okay, here's your task for now. I'd like you to fill in the following table. I'm going to do the first one for you just to get you started but then I'd like you to do the rest. So we need to do this by deduction. We've got 7 protons. We know that the atomic number is the same as that so that's going to be number 7. The mass number is the protons plus the neutrons that's 7 plus 6 which is 13. The charge here is the positive charge from the protons plus the negative charge from the electrons which is going to be 7 minus 7 which is 0 so this is a neutral atom. Now we need to look up the name and symbol. We know that the atomic number is 7 so we go to our periodic table and we look for atomic number 7 and we find that it's nitrogen. So the symbol is N, the name is nitrogen. To complete the symbol we put the atomic number at the bottom left and the mass number at the top left and because this is a neutral atom we don't need to write a charge. There we go. I'll leave the rest for you to finish off.
