Polonium is a radioactive element that exists in two metallic allotropes. The alpha form is the only known example of a simple cubic crystal structure in a single atom basis, with an edge length of 335.2 picometers; the beta form is rhombohedral.olonium is a very rare element in nature because of the short half-life of all its isotopes. 210 Po, 214 Po, and 218 Po appear in the decay chain of 238U; thus polonium can be found in uranium ores at about 0.1 mg per metric ton (1 part in 10 10), which is approximately 0.2% of the abundance of radium.
Thus, its complete electron configuration is 1s2, 2s2 2p6, 3s2 3p6, 4s2 3d10 4p6, 5s2 4d â¦ 10 5p6, 6s2 4f14 5d10 6p4. From this, we see that its highest number shell, which is its valence shell is 6. Thus the valence electron configuration of polonium is 6s2 6p4.ince gallium's atomic number is 31, we know that it has 31 protons and 31 electrons. Thus, its complete electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p1. From this, â¦ we see that its highest number shell, which is its valence shell is 4. Thus the valence electron configuration of polonium is 4s2 4p1.
