Last week, you were told you have a new boss. Your new boss has a science background but he hears that beryllium (Be) is much cheaper than lithium. Your team does not think that switching to beryllium in batteries is a good idea. You have a meeting coming up with him. You plan to convince him that lithium is a better choice than beryllium for creating lightweight, and energy efficient batteries. Use your knowledge of periodic trends to create a slide with your team to present to him! Use the following concepts and terms in your argument: ionization energy, Does Li or Be have a greater ionization energy? Why does this matter? atomic mass Does Li or Be have a greater atomic mass? Why does this matter? Conclusion :arrow_forward
