This periodic law was stated by Henry Moseley, not by Dimitri Mendeleev
I think this article made a mistake in the trend for nuclear charge; this says nuclear charge increases as you go down a group (column), but other sources (nothing really citable, just my son's class notes and a Yahoo! answer post) say nuclear charge decreases down a column.
I don't want to edit this article, because I'm just a mom checking my son's chemistry homework, and I'm not completely certain about this.
Perhaps someone more knowledgeable would be willing to edit this article, correcting this and any other factual errors?

I'm not well enough versed in Chemistry to add this section but, I did come to this page looking for this information so I would like to see it added in the future. Perhaps also periodic trends in acid bases strength.

It would be nice to at least mention Mendeleev's work? He found the trends, so. — Preceding unsigned comment added by 98.200.209.118 ( talk) 02:28, 8 March 2013 (UTC)
The article starts off "In chemistry, periodic trends are the tendencies of certain elemental characteristics to increase or decrease as one progresses along a row or column of the periodic table of elements." This seems completely wrong-headed to me, and completely misunderstands both the common and scientific meanings of the word "periodic", and why the "periodic" table is so called! "Periodic" things are those which repeat themselves at regular intervals. The "periodic trends" which Mendelev famously noted in the elements (when arranged in increasing atomic weight) were recurring similar properties. It was on the basis of these recurrances that Mendelev decided where to break the table into a new column or row. In other words, the "definition" in the article is ass backwards. -- feline1 ( talk) 11:56, 17 February 2014 (UTC)

It was
proposed in February 2016 that
Periodic Law be merged with
Periodic trends, but no discussion was started so I am adding this section to hold the discussion.

The options here:
I note that the trends article is longer and older, having been around since 2006; the Law article is shorter and has only been an article since February 2016, although it was a redirect to History of the periodic table since 2005. I note that Periodic law (with a lower case "l") was also a redirect to History of the periodic table (since 2004), but was changed to point to Periodic table in 2007 and in 2008 to § Periodicity of chemical properties and finally, in 2015, to Periodic trends when the section was expanded into a separate article.

It looks to me like a consensus to merge into periodic trends. I am going to do this in a rather simple-minded way as follows
I will leave the additional wordsmithing and merging to subsequent editors. YBG ( talk) 03:58, 22 August 2016 (UTC)
