CHEMISTRY PROBLEMS Calculate the characteristics of each particle: The most common isotope of oxygen is an atom with 8 protons and 8 neutrons. 1. A. B. C. D. 2. A. B. C. D. 3. A. B. C. 4. A. B. C. D. 5. A. B. C. What is the mass of this isotope? How many electrons are in an atom of oxygen? Another isotope of oxygen has 7 neutrons. What is this isotope's mass? How many electrons are in an oxygen ion with a charge of -2? The most common isotope of carbon has a mass of 12. Carbon has an atomic number of 6. How many protons are in an atom of carbon? How many neutrons are in an atom of carbon? How many electrons are in an atom of carbon? Another isotope of carbon has a mass of 14. How many protons, neutrons, and electrons are in this isotope? A chlorine atom has 18 neutrons and an atomic mass of 35. How many protons are in the chlorine atom? If the atom forms an ion with a charge of -1, how many electrons are in the ion? How many electrons were in the atom before it formed an ion? Nitrogen atoms have 7 protons. How many electrons are in an ion with a charge of +5? How many electrons are in an ion with a charge of -3? If nitrogen atoms also have 7 neutrons, what is the mass of nitrogen? How many electrons are in an isotope of nitrogen with 8 neutrons? Hydrogen atoms have 1 electron and a mass of 1. How many protons are in hydrogen atoms? When hydrogen forms an ion with a +1 charge, has it gained or lost electrons? How many electrons has it gained or lost? When hydrogen forms an ion with a -1 charge, has it gained or lost electrons? How many electrons has it gained or lost?
