for the third day of Christmas, we got something quite special.

基礎被動語態

The one that was given to me this year is the 3rd 1 here, which has the element tin on it.

The element in is number 50 on the periodic table.

These pins all come from Moscow State University, where I'm an honorary professor.

For the last 50 years they've celebrated the day of the chemist Yeon Hee Mika.

For the 1st 1 they had a badge with hydrogen on it.

And then each year they've gone one place along the periodic table.

The first time I came across it was in 1990 when they got to Element number 25 which is my Lipton, Um, and I got to pin then and then in 1991 I got another one iron, which is 26.

I have had a few, but this year's number 50 and I got a special gold one.

I also got a book which shows all of these badges hydrogen, helium, lithium and so on So you can see here my militant them and I in batches they haven't got the color's quite right for the iron.

I've got a special addition, Gold one, whereas ordinary people got colored one.

It's really nice that any chemistry department should have such a long tradition every year celebrating chemistry.

So for the third day of Christmas, we have three chemical badges to periodic table bed covers on one piece of Toto Eric acid from a Swiss wine barrel.

I got up to a few other adventures in the way I'm guessing that this here is representing the Earth.

Correct on this golden orb here in the middle, Mr Sun?
