Final answer:The element denoted by theelectron configuration[Kr] 5s2 4d10 5p3 is Antimony (Sb). This is because the total number of electrons (51) equals the atomic number of Antimony in the Periodic table.Explanation:The electron configuration here is [Kr] 5s2 4d10 5p3. Krypton (Kr) in this configuration signifies theelectronconfiguration of the noble gas Krypton (Kr), which replaces the need to write out the first 36 electrons. We then add the rest: 5s2 adds 2 more electrons, 4d10 adds another 10, and 5p3 adds another 3. Adding up all the electrons (36 for Kr, 2 for 5s2, 10 for 4d10, and 3 for 5p3), we find that the total number of electrons is 51.Aneutralatom will have the same number of electrons as protons, so an atom with 51 protons is Antimony (Sb) in the Periodic Table. Therefore, theelementdenoted by the electron configuration [Kr] 5s2 4d10 5p3 is Antimony (Sb).Learn more about Electron Configuration here:brainly.com/question/31812229#SPJ3...
