Elements
Which of the 118 elements this list accounts for, laid out where a chemist expects to find them.
In the list
88
of 118, and referenced by EF 3.1
Unreferenced
4
a flow object exists; nothing in EF 3.1 points at it
Not in the list
26
no flow object carries this atomic number
The elements a flow list is missing are not a random selection: they are the short-lived transactinides at the bottom right, which no inventory has ever emitted, and a handful of others that are a scope question rather than a gap. Laid out as the table, that is visible at a glance; stated as a count of uncovered elements, it says nothing at all.
A cell that links has a flow object. n is how many nuclides of that element the list carries and i how many ions — both are flow objects in their own right, and both are on the element’s page.
