Lanthanide - Wikipedia
The dicarbides with exception of EuC 2, are metallic conductors with the calcium carbide structure and can be formulated as Ln 3+ C 2 2− (e–). The C-C bond length is longer than that in CaC 2 , which contains the C 2 2− anion, indiing that the antibonding orbitals of the C 2 2− anion are involved in the conduction band.

Amazing Rust - Flame Test
25/9/2017· Some colors are very weak and are easily overpowered by stronger colors. For instance, the presence of a potassium ions (K + ) in a compound will color a flame violet / lilac, on the other hand, even trace amounts of sodium ions (Na + ) in a compound produce a very strong yellow flame, often times making the potassium ion very difficult to detect.
