Vanadium

Hi there. After a long break, I am back at chemistry articles :) Currently working on vanadium in Turkish. I was checking the data on the abundance of elements in Earth's crust article, and I found a source saying that the abundance of vanadium is 0.019% of the Earth's crust and that puts the element on the 18th place ("The potentiality of vanadium in medicinal applications", Dieter Rehder). But the article doesn't mention any source for that value. Do you think we should mention on that? Or should we ignore? Nanahuatl (talk) 02:02, 20 December 2023 (UTC)[reply]

@Nanahuatl: WebElements agrees that vanadium is 18th, but not CRC. That said, I suspect uncertainties are large enough that one cannot really give an exact number. Double sharp (talk) 04:07, 20 December 2023 (UTC)[reply]

Is it a reliable source? Nanahuatl (talk) 04:29, 20 December 2023 (UTC)[reply]

@Nanahuatl: Well, it says that the data is averaged from eight reliable sources that differ widely from each other. So I think it's probably best to not give a figure, and instead say that V is pretty common and list a common element V is close in abundance to, like Cl.

And per "Thermophysical properties of vanadium at high temperature measured with an electrostatic levitation furnace", the density of solid vanadium is 5.7 g/cm³. Yet, the article says 6.11. Can you check that value too? Nanahuatl (talk) 05:55, 21 December 2023 (UTC)[reply]
