Periodic table of data

I found a link to this on Twitter, part of last weeks National Periodic table day. This is a really useful set of periodic tables, each one covers a different topic, e.g Origins, name origins, elements in the Sea, Phones, Toxicity etc.

So an example is:– Periodic table of Isotopes, which gives information on how many isotopes there are for each element.

The search for life on Mars

One of the advantages of being a higher education student or in my case alumni is you get to join groups. I have just been watching a live webcast on the experiments that are being used onboard Mars rovers to look for possible indicators that Mars once supported life.

Exploring the Habitability of Mars with the Curiosity and Rosalind Franklin rovers and Orbital Missions

I am not sure if there is a recording of this going up, but the link to a some more information is here.

I am currently undertaking Particle Physics but there is also a really interesting series of lecutures on AstroBiology I want to check out too.

Meteorites Talk

Just been watching a really interesting talk by Dr Tim Gregory – Meteorites from 8th October 2020 – YouTube.

This was really interesting and accessible people with both a science and non science background,

Briefly touched on how the solar system was formed, protoplanetary disks looked at the two different types of asteroids, how they are formed, what makes them up internally, and finished off with a quick look at some of the organic molecules that have been found and how these could have found their way to earth.

Well worth a look, the video can be found on Youtube.

Thank you to the OU Science Club for pointing me to this talk.

National Chemistry Week 2020

18th to 24th October is National Chemistry week, so there are a few activities listed on the American Chemistry Society website out reach pages.

In recent chemistry news ScienceMagazine has an article on a Globular cluster in the Andromeda galaxy that appear to be deficient in elements heavier than Hydrogen and Helium.

This is interesting, there isn't that much information due to the need to sign in, but I would suspect the research papers may be more widely available in due course.

Organic Chemistry 6: Benzene Derivatives in Organic-Chemistry

So as an extension to yesterdays post Compound chemistry have an infographic on Benzine derivatives.

So once you have made a Benzine molecule, this can be easily modified to some of what is presented here.

Organic Chemistry: 5 Phenyl Group

As Polystyrene Contains a C6H5 Phenyl group. Before moving on to building this, we can look at similar molecules that also contain this group.

Video should show making of the above compounds with Molymod components.

Tomorrow, I will post a follow up on more benzene based molecules to build. So please keep hold of the C6H6 Benzine model.

If you would like any further help with chemistry (or any other science subject) then I have found ScienceForums to be a very useful, friendly and educational forum.

Organic Chemistry 4 : Plastics

Previous post

Moving on lets have a look at:-

I have built this using Molymods in the video below, Just imagine that the rest of the white atoms (hydrogen from previous video) are in fact green, Chlorine atoms.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

I will post a few more videos showing the other molecules in that section of the infographic.

**Note: ** Polytetrafluoroethylene. It appears that Polytetrafluroethylene and Polytetrafluroethene are the same molecule, with different spellings depending on if you're using US or GB English.

Organic Chemistry 3 Plastics

Following on from organic-chemistry-2 we have had a look at Alcohols. So will now turn some attention to plastics.

So again we can construct models of plastics in a similar way, the main difference here is that plastics are POLYMERS, which are MONOMERS chained together.

Mono – Single Poly – Multiple

So looking at the above you will notice that they are using n to indicate there is more than 1 in the chain.

So starting with ${C2H2}$ or Ethene, this becomes Polyethene when more monomers are added to the chain.

So in the video below, I construct Ethene and then, in the spirit of Blue Peter, I am then using a few more I made earlier.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

I will post a few more videos showing the other molecules in that section of the infographic.
