Tennessine – Periodic Table of Videos

published on July 17, 2020

There may be a slight argument about how you pronounce the name of element 117 I would pronounce it 10 the scene like iodine and chlorine but some people in America say chlorine and iodine but my feeling is that everybody will say tennis scene because it sounds just like

The state of Tennessee whereas tennis sign doesn't the reason why it was called Tennyson is because Tennessee is the home of the Oak Ridge National Laboratory where the berkelium that was used to make the element to

Synthesize it the heavy target was made out of berkelium and the berkelium sample was prepared in Oak Ridge then as before we accelerate a light atom calcium 48 a very expensive isotope of calcium into the book helium and make

Element 117 Tennessee now I think that the interesting things about Tennyson is to speculate about the chemistry the first thing is that you could wonder about its color if you could get a large lump of tender seen if you'll go down

Group 17 fluorine is almost colorless slightly green and then as you go to bromine is red iodine is a dark purple color nobody knows what astatine looks like and it's possible that Tennessean might be a black gas which would itself

Be really quite exciting now unfortunately the way these experiments are done is that although you would expect Tennessee and being a halogen to exist as two atoms Tennyson – just like CL – you only make one atom at a time so

It's like some rare species of animal there's just one in the zoo and you can't find a mate so we'll never know what Tennessee – looks like because we can never get two atoms at the same time I would predict that

Menacing to would have a very weak bond possibly the weakest bond between two atoms of the same type that actually bond together for example helium doesn't bond to anything but it would be a very very weak bond the other thing which is

Interesting is to have a flight of fancy imagine what some of the compounds would be like and the one I would really like to see is francium tennis I'd a bit like sodium chloride but with francium the element which loses an electron most

Easily from the alkali metals and telecine and I would predict that francium tennis I'd would form crystals which are really quite flexible if you take caesium iodide higher up the periodic table you can bend crystals of

Cesium iodide without breaking them you could probably make Springs out of France in tennis I'd but it's so radioactive that you would be got by the radioactivity long before you make the spring

And there we have nearly two inches maybe of liquid fur and you can go right up that's there's no problem with that you want to just clear a bit of condensation off there yeah I'm really surprised I thought it would be pale

Green and it's really quite dark yellow if I'd been shown it I would have said it was liquid chlorine I never seen liquid chlorine either quite through that I have been as for insectary giving quite a few of my notes and things to

Keith to put in the archives so there will be at least some trace of me even if you can't read my emails
