Th + e – → Th – – ∆H = Affinity = — kJ/mol. The electron configuration of thorium is [Rn] 6d27s2. Thorium is an important alloying element in magnesium, imparting high strength and creep resistance at elevated temperatures. Thorium is a lanthanide (rare earth) material with potential nuclear power applications. it extremely is the reason each and each element has a special atomic form. Electrons per shell: K2, L8, M18, N32, O18, P10, Q2. Top. The nucleus consists of 90 protons (red) and 142 neutrons (blue). Thorium (Z = 90) has the atomic ground-state electronic configuration of [Rn]6d 2 7s 2 with a partially occupied 6d-shell and an empty 5f-shell located inside the outer 7s-shell. Electron configuration: 6d27s2 But according to aufbau principle, the electrons should first enter f subshell and not d subshell. purely the style of protons interior the nucleus determines the id of the element. Because thorium has a low work-function and high electron emission, it is used to coat tungsten wire used in electronic equipment. Thorium in +3 state not very stable it will oxidise into +4 oxidation state. If you don’t have a chart, you can still find the electron configuration.
