On the issue of numbering the shells of the layers of the electron cloud of atoms[edit]

In my opinion, it would be better to start the shell number of the electron cloud layer of the atom l not from zero, but from one. After all, the number of shells in a layer is equal to the layer number. The tradition of numbering shells from scratch, inherited from the beginning of the 19th century, is in contradiction with logically understandable numbering: 1, 2, 3, 4, 5, ... The number zero can be perceived as the absence of what is numbered in natural numbers. Alex makeyev (talk) 21:50, 9 February 2024 (UTC)[reply]

We can interpret the reason for the properties of halogen in hydrogen and the properties of noble gas in helium in this way. The missing p-shell in the first layer of the electron cloud of hydrogen and helium atoms is replaced by its s-shell for two finite elements of the virtual p-shell.

This is essentially no different to the breakdown shown in the Classification of elements section. — Sandbh (talk) 00:19, 3 March 2024 (UTC)[reply]

Strange lede sentence[edit]

Is it just me, or is it a bit strange to have the lede sentence describe the subject in a verb form (the periodic table arranges) instead of a noun form (the periodic table is an arrangement)?

I propose that the lede sentence should be changed to: The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups").
