A mass spectrometer is an instrument that allows scientists to determinethe presence of elements in a given sample. As an environmental scientist, youhave analyzed some samples in a mass spectrometer and have found the presenceof elements. Now, you must organize and label some of the elements that youdiscovered in the samples. They are C, Po, Cr, Mg, and B. 2.In the table below, classifyeach element by the group (metal, nonmetal, or metalloid) it belongs to. Element Group C nonmetal Po metal Cr Mg B 3.A material chemist is tasked with coming up with a new material thatwill have specific, desired properties. A compound that she is working oncontains magnesium. A common approach to create a compound with enhanced,desired properties is to change one element in the material at a time. In thiscase, the material scientist will often try to change it with an element fromthe same Group in the periodic table. Forthis exercise, you will do the following: Complete the table below by labeling each…
