Actinides

welcome!

Welcome to ER and JK's wiki! This wiki is observing seven actinides(as we will call them) or actinoids. We will offer several facts on the elements we have information on. In addition we also have a sltde show that will cover all the key facts for each element. I hope that you enjoy this wiki!

-ER

Einstienuim-

Einsienuim was first discovered by Albert Ghiorso in 1952 at University of California Berkly. This element is radioactive. Einstienuim is an actinide. Which means it is between Actinium and Lawrencium. Einsteinuimn han the atomic number 99. Some forms of Einstienuim have been comfirmed as isotopes. An isotope is a element with same number of protons and nucleus but not nuetrons. Einsienuim is silver. It has no known uses.

Additional information-

Doesn't occur naturally

Melts at 860 degrees celsuis

Half life of 275 days

Atomic symbol Es

Nobelium-

Nobelium was first correctly identified at Flerov Labrotory in Russia. Nobeluim is a radioactive element. Some compounds of nobeluim nhave found to be isotopes.

Nobeluim 's atomic number is 102, which means nobeluim is actinide. The color of nobeluin is most likely a silvery color.

Additional information-

unknown melting point

discovered in 1959

Mendelevium-

Mendelvium is the third to last actinide, Lawrencium is the last and Nobeluim the second last. Mendelvuim is a synthetic element. It was first synthesized by Albert Ghiorso. Mandelvuim melts at 1100 degrees kelvin. It is a synthetic element.

Lawrencium-

Lawrencium is the last actinide on the periodic table of elements. This element is radioactive. Lawrencuim has no known color, but scientist hypothisize it is a grayish color. Lawrencium has ythe half life of 3.6 hours. Lawrencium has the atomic number of 103.

Additional information-

Discovered by Albert Ghiorso

Americium-

Americium has the atomic number of 95. Scientist s have comfirmed that the color of this element is white. Americium melts at the temperture of 1449 degrees kelvin. Americiuim is a synthetis element. This element is also radioactive. You would be suprised to know that americium is used in the smoke alarm! Imagine that.

Actinium-

Actinium is the first of the actinides and also the name sake. Actinium is a transition metal. It was discovered by a french chemist, Andre-Louise Debeirne in 1899. It is also named after him. The color of the element is silvery. This element melt at the temperture of 1323 degrees kelvin.

Additional information-

atomic number 89

Thorium-

Thorium is the second actinide or actinoid on the periodic table. This element is one of the few actinides that have uses. Thorium is used to alloy magnesuim!

The state of matter for this element is a solid. The melting point for this particular element is 2115 degrees kelvin! This element is named after the nordic god, Thor. Thorium can also be used as a nuclear fuel! THis element is also radioactive.
