Motivation[edit]

The value is helpful in understanding molecular/crystal structures and thus their reactivity. Since it can be helpful for use in the Wikipedia (i.e. to generate graphs such as a scatter plot on this page) and outside of it. The Qualifiers charge number (Q1800063) and coordination number (Q397226) are needed, molecular geometry (Q911331) is only in a few cases necassary. I hope I filled the form right, if there are any questions, please ask. Meinichselbst (talk) 19:53, 18 April 2022 (UTC)[reply]
