ELEMENT 90 of the Periodic Table, thorium, ordinarily appears as the first element of the actinide series, appended below cerium at the bottom of Table 1. This construction gives the impression that thorium is
Similar to uranium, thorium can be used as a fuel in a nuclear reactor and is a key factor in the sustainability of nuclear energy. Much of the earth’s heat is attributed to the decay of both uranium and thorium. When exposed to air, the element retains a silverish whi...
preceding paragraph notwithstanding, I traded this sample for the next one listed under thorium, a square rod in a glass ampule. OK, not just for the rod, I got something else that must remain confidential for the time being, but will show...
It seems I guessed right about the correct method for shipping thorium, because these people certainly know what they are doing. I chose this sample to represent its element in myPhotographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which yo...

A thorium atom has 90 electrons, of which four are valence electrons. Three atomic orbitals are theoretically available for the valence electrons to occupy: 5f, 6d, and 7s. Notwithstanding its position in the f-block of the periodic table, it has an anomalous [Rn]6d2 7s2 electron confi...

There is continued burgeoning interest in metal–metal multiple bonding to further our understanding of chemical bonding across the periodic table. However, although polar covalent metal–metal multiple bonding is well known for the d and p blocks, it is relatively underdeveloped for actinides. Homo...
