Chemistry Summer Project: Help! (periodic table)?

Question

This is my assignment:

Research Dmitry I. Mendeleyev’s invention of the Periodic Table. How has the table changed since its 19th century inception? Create an illustrated timeline of the table’s changes on a standard size piece of printer paper. You may use images from the web if you want to.

4. What’s in a name? How did the elements of the Periodic Table get named? Learn the stories behind several of the elements’ names and then choose a few (at least three or more) that you find most interesting. Create an illustrated display on a standard size piece of printer paper portraying the elements’ stories in a creative manner.

Do you have any websites that show the introduction of elements after Dmitry I. Mendeleyev’s. I'd really appreciate it. Please attach legitimate links....tyvm.

God Bless.

Answer 1

This is the online version of my Science Textbook which I'm using currently. Just visit this. I don't know the exact answer that you want as they haven't yet thought me this Chapter. http://www.ncert.nic.in/textbooks/testing/Index.htm



Just select the Class X, Science, Science. Now, press "Go" button to the right and let the book download. It will download in the form of Adobe Acrobat. Click Chapter 5. Let it download for sometime. Just flip pages and I think you'll find the answer...

Answer 2

First link: general overview.

Second link: Each element has overview of chemical properties, year discovered, and person who discovered it. (sorted by year discovered.)



The last will be most helpful to you though.
