Element T has an oxidation number of -2 (it needs 2 more electrons to become stable). Element U has a larger atomic radius than element Q. Element U does not follow the periodic trends like the other group A elements do. Element M is more electronegative than element O. Element Y is the most metallic element on this chart.

Feb 03, 2016 · As a result, you can determine the number of protons an element has from the atomic symbol if you have a periodic table handy. The atomic mass is also different for every element, and also for isotopes of the same element. The atomic mass is equal to the number of protons that an element has plus the number of neutrons that an element has.
