Explanations[edit]

hey everyone i need to understand this. anybody want to help me? —The preceding unsigned comment was added by 168.37.196.2 (talk • contribs) 14:28, 5 November 2003 (UTC).[reply]

What is development of alkaline earth metal? —The preceding unsigned comment was added by 210.213.139.128 (talk • contribs) 11:24, 8 August 2004 (UTC).[reply]

I don't understand your question. Do you mean that you have a homework assignment that says "Describe the development of alkaline earth metals" or something like that? If so, the answer is "It depends what you mean by 'development'." -- Heron 15:55, 8 Aug 2004 (UTC)

Magnesium[edit]

Magnesium will react with hot water, liberating hydrogen, I have done it. —The preceding unsigned comment was added by 12.10.127.58 (talk • contribs) 14:22, 10 August 2005 (UTC).[reply]

Did you do it at 1atm? At 1 atm Magnesium metal only reacts with steam (hot water vapor from boiling) —The preceding unsigned comment was added by 65.93.214.8 (talk • contribs) 02:46, 30 September 2005 (UTC).[reply]

Ibrahim Samad Afridi: Magnesium and calcium are the most common alkaline earth metal.Metallic bonding in these metals involve two electrons .Therefore these metals are soft but are much harder than alkali metals.They are relatively reactive but less reactive than alkali metals magnesium reacts with steam but calcium reacts with cold water. — Preceding unsigned comment added by 182.177.66.104 (talk) 13:53, 22 May 2012 (UTC)[reply]

Physical & chemical properties, beryllium & important reactions/compounds[edit]

The content of this article is good in my opinion. In to order to complement the existing information, I thought it would be a good idea to add some information talking about the physical and chemical properties of these elements. I found it was also important to talk about beryllium since, as I mentioned in my text was "special". Finally I decided to add some important reactions and compounds in order to understand in depth the alkaline earth metals. —Preceding unsigned comment added by Babychanel (talk • contribs) 22:59, 16 June 2009 (UTC)[reply]

I made a couple of changes where "alkali metal" was used where "alkaline earth" was meant. Also for some reason "ununennium" popped in as the second element in period eight and the second not yet discovered element; the first is unbinilium and, since the synthesis of ununseptium, so is the second.Syd Henderson (talk) 00:37, 2 April 2011 (UTC)[reply]

Orphaned references in Alkaline earth metal[edit]

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Alkaline earth metal's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "EB":

  • From Sri Lanka: "Cinnamon". Encyclopædia Britannica: Cinnamon. Encyclopædia Britannica. 2008. (species Cinnamomum zeylanicum), bushy evergreen tree of the laurel family (Lauraceae) native to Bangladesh, Sri Lanka (Ceylon), the neighboring Malabar Coast of India, and Myanmar (Burma), and also cultivated in South America and the West Indies for the spice consisting of its dried inner bark. The bark is widely used as a spice due to its distinct odor.
  • From Alkali metal: Seaborg, G. T. (ca. 2006). "transuranium element (chemical element)". Encyclopædia Britannica. Retrieved 16 March 2010. {{cite web}}: Check date values in: |date= (help)

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT⚡ 03:33, 12 April 2012 (UTC)[reply]

Beryllium, magnesium excluded[edit]

Mention somewhere beryllium and magnesium are sometimes excluded, thus the group sometimes begins at calcium.--R8R Gtrs (talk) 19:04, 12 June 2012 (UTC)[reply]

A ref: [1] When Be and Mg are excluded from group 2, they're sometimes included in group 12 instead. Double sharp (talk) 07:32, 14 June 2012 (UTC)[reply]

Non-linear molecules[edit]

Just pointing you into this paper: http://131.104.156.23/Lectures/CHEM_462/7113_Literature/ic00113a023.pdf . If I were to write the thing, I'd definitely use it somehow (no major accent, but you wouldn't maybe find the paper yourselves guys... I wouldn't at least, found it accidentally)... No biggine... but a nice by-the-way (two or three sentences) addition--R8R Gtrs (talk) 23:50, 19 August 2012 (UTC)[reply]

Thanks! I'll add this in soon. StringTheory11 (t • c) 23:56, 19 August 2012 (UTC)[reply]

History of strontium[edit]

I updated the history section of strontium an eliminated the misconception that Hope named it.--Stone (talk) 23:17, 26 November 2012 (UTC)[reply]

Eka radium[edit]

Is it just me, or is it undue weight to devote one of the three paragraphs in the lede to an element that does not exist?

Rwflammang (talk) 19:41, 21 October 2013 (UTC)[reply]

It's kinda interesting that it might not behave like the lighter alkaline earth metals, which increases its notability. Double sharp (talk) 02:01, 22 October 2013 (UTC)[reply]
This undue weight and interesting. But I think it can go to a lower section of the article. This is not what anybody is searching for. Wikipedia is a place were you search for certain information and not for interesting things. --Stone (talk) 11:25, 22 October 2013 (UTC)[reply]
I dunno honestly. It certainly could work in the lede, as it is not everything we predict about E120 and this is just a summary. See the lede for alkali metal (E119, similar case). But the lede here hasn't been expanded so it does not fit well. We really need a separate section for this. Double sharp (talk) 14:50, 22 October 2013 (UTC)[reply]
The problem is that in the lead there should be a small condensed version of the maintext. Refs should only be used if it is controversal. Second point in the alkali metals article is 300 of 3000 words while in the alkaline earth it is 400 of 1000 words.--Stone (talk) 18:30, 22 October 2013 (UTC)[reply]

Assessment comment[edit]

The comment(s) below were originally left at Talk:Alkaline earth metal/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

For B-Class is necessary:
  • comparison of reactivity
  • comparison of compounds
  • occurence section
  • production section
  • although part of biology already, a few words on precaution comparison
  • a history section would also be nice

Move discussion in progress[edit]

There is a move discussion in progress on Talk:Alkali metal which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 06:14, 28 February 2019 (UTC)[reply]

Singular[edit]

@Amakuru: How do you propose to make the introduction singular? (You moved the article back) Christian75 (talk) 07:38, 11 February 2022 (UTC)[reply]

@Christian75: there is no particular requirement that the bolded term in the article lead has to match the title of the article when it comes to singular/plural. The lead would be phrased in the way that best introduces the topic, which this one currently does. See for example mammal, which is about a class of animals and whose lead uses the plural, but where the title is singular. While the title is expected to conform to overall titling policies, and in particular to consider whether the term is predominantly considered plural or singular in sources. In the case of alkali metals, (and probably therefore alkaline earth metals too), the two terms are virtually tied in book usage, which means that our general preference for the singular from WP:NCPLURAL should apply. Anyway, the bottom line is that this was discussed already at Talk:Alkali_metal#Requested_move_28_February_2019 and there was no consensus to move it, so if you wish to make a move you'll have to propose it at a fresh WP:RM discussion and provide evidence as to why the current set-up is wrong.
