Feeling like sunshine! That could probably kill you...


Status update:

9 year anniversary since I got banned from Europe... I'm not that poisonous, am I?   10-9-13

Don't you love being a quarter of a circle in the top right corner of a masterpiece? Because I sure do!   10-10-13

Silver and I are going to go get 'soldered' up! Those Aluminum tubes just won't stick together, so they called us in!   10-11-13

I think Telluride and I make the perfect couple. People need us to be together for Infrared lenses and Solar Cells, but I think that that's not the only reason we're together. <3   10/29/13

I love chemical equations! It's like being on a seesaw, and the solver gets to do trial and error, like pushing me up and down on the seesaw. It's actually really easy, once you get the hang of it. Being an element, I've seen tons of people struggling, but it's all worth it, because you get the answer in the end!    10/29/13


I am Cadmium, a poisonous metal that is the byproduct of refining Zinc. I am solid at room temperature, but my melting point is 610°F. My atomic number is 48 and my atomic mass is 112.411 amu. I was mostly used as yellow and red pigment for paint, until people found out I was very poisonous. Then, they started using me for batteries with my good old friend, Nickel and even fertilizer! Now, I'm simply another old element of the Periodic Table. 



Relationship Status: 

In a relationship

Primary Relationship: 




valence electrons:


reactivity: More reactive than Hydrogen, but less reactive than Carbon. Reacts with most acids. 
state of matter:  Solid 
Location on Periodic Table: Group 12, Period 5

The Yellow Poison 

Activities & Interests:

I love to participate in nuclear fission, especially to help be the barrier that has to control those random fun neutrons! I love that job, even though the neutrons tickle a little. I also like to conduct electricity with Nickel, but being in those batteries can be boring, yet I still think it's alright if Nickel is with me. And finally, I saved the best for last: being in paint! All the painters loved me because I made the most brightest yellows, reds and oranges for them. They even said I lasted long too! I am also found in tobacco in cigarettes and can accumulate in people's bodies. Humans even let me be in fertilizer, but I don't get it, I thought they didn't want me to poison them. 



I visit my home in Siberia a lot, even though people think rivers aren't the best homes for metals like me, I don't mind, because being at the basin of Vilyuy River is great. When I think about it, I'm actually pretty rare compared to Zinc, Lead and Copper. I live at about 0.1 ppm (parts per million) in the Earth's crust. Almost all the time I'm combined with some of my friends from the Periodic Table, mostly Zinc. Only humans can purify me, and you can never find my pure form out in the wild.    10-10-13  Also, people say I could be found in Germany where Hermann and Stromeyer found me.    10-11-13

Create 2 photo albums:

  • atom and bonding diagrams - these will be done in class and will take time
  • fun images - pictures that contain the element

 every photo must have a caption 

- tag other elements in the pictures

High purity of me. I look like a crystal, don't I?

You said that you were part of a masterpiece...what masterpiece would I find you on?

I mean I am part of a painting or artwork. My bright vibrant yellow colour makes me the perfect choice to paint the sun (usually in the top right corner of the page).

Tellurium and I are going on a date soon: a picnic on the roof of a building, soaking up the Sun. What else are we going to do, if we're going to go as Solar Cells? It's really great though, and we have a covalent bond and slight ionic character. It's as if we were made for each other <3

I am so happy that we are now in a relationship! Together forever! <3

We make a covalent bond together! We are such a great team together; you and I form a film that converts sunlight into energy! How cool! <3
