Oppose. I do not see (in the proposal) what is the problem with current name. "This is the primary topic for the proposed title": no it is not. This period is not only chemistry, it is also covering physics (think electron configuration, isotopes). So cutting physics out of its meaning is not an improvement. I note that the use of wording "primary topic" in your post is not the same as WP:PRIMARYTOPIC since it is not about change of topic (article). WP:PRIMARYTOPIC is about deciding between two different topics with same (prospect) title. In that case, one can look for one being the primary.
Next, you write: In chemistry, "period" usually refers either to this or to a time period: IOW, "Period (chemistry)" does not disambiguate! Instead, it would require disambiguation like "Period (chemistry, periodic table related)", "Period (chemistry, time related)".
The article actually hurt by this move is: Period (periodic table), because its article title would be made incorrect and ambiguous.
The considerations for Group (periodic table) I do not understand. Anyway, a name change for that page cannot be made in this thread.
There is a bigger argument for current name. That is: the word "period" in Period (periodic table) and in Periodic table stem from the same base: periodic law. The period we ar talking about originates from the periodic table. So using that disambiguation term is most appropriate and least confusing. WP:DAB says, in point 3: [Add in parenthesis] the subject or context to which the topic applies. -DePiep (talk) 16:02, 3 February 2019 (UTC)[reply]
Oppose per DePiep; the current title is most precise for the article's subject, while the proposed destination is more ambiguous as there are other types of periods in chemistry and physics, which could lead to some unpleasant WP:SURPRISEs. If anything, we can add a hatnote to period (disambiguation page) where other uses are listed. ComplexRational (talk) 16:33, 3 February 2019 (UTC)[reply]

The marking you do in periodic table image is wrong correct one is periods -horizontal[➡️] and groups vertical[ ⬇️]
@Sose69: In the periodic table of the elements, each numbered row is a period. Do you mean this image? It is clearly labelled with "Group" pointing to the group numbers at the top of each column along the top edge;, and "Period" pointing to the period numbers at the start of each row down the left edge. It also states each numbered row is a period. Are you saying this is incorrect? Bazza (talk) 10:42, 19 January 2024 (UTC)[reply]
