P3+Actinides

The period our elements are in is period 7. The groups our elements are in is 3-16.

There are multiple elements in our group of elements.


 * Actinium- GAS
 * Thorium- GAS
 * protactinium-GAS[[image:file:///Users/cory/Desktop/Picture%202.png]]
 * uranium- GAS
 * neptunium-GAS[[image:http://t1.gstatic.com/images?q=tbn:wsQJ4rGhp4fcAM:http://central.sancarlos.k12.ca.us:16080/%7Ernielsen/projects/reid/periodictable/Einstinium_files/b0099.jpg width="217" height="217" align="right" link="http://images.google.com/imgres?imgurl=http://central.sancarlos.k12.ca.us:16080/%7Ernielsen/projects/reid/periodictable/Einstinium_files/b0099.jpg&imgrefurl=http://central.sancarlos.k12.ca.us:16080/%7Ernielsen/projects/reid/periodictable/Einstinium.html&usg=__kwKlMHHZ9KUxNRcenFFv46XgQeQ=&h=264&w=265&sz=39&hl=en&start=34&tbnid=wsQJ4rGhp4fcAM:&tbnh=112&tbnw=112&prev=/images%3Fq%3Dactinides%26gbv%3D2%26ndsp%3D18%26hl%3Den%26safe%3Doff%26client%3Dfirefox-a%26rls%3Dorg.mozilla:en-US:official%26sa%3DN%26start%3D18"]]
 * plutonium-GAS

 * curlum-GAS

 * nobelium-UNKNOWN

A common chemical property that this element has is oxidation state. An actinides element is known for having many oxidation states. All these elements are radioactive heavy metals positioned at the bottom of the Periodic Table. They have a strong chemical connections to their homologs in the lanthanide group. There are ideas of the existence of this state in some elements heavier than californium. Actinides are unstable and are produced only artificially. Their atoms have similar configurations and similar physical and chemical behavior.

__Interesting facts__
 * Only four of the elements in this group were found in nature.
 * Some of the elements are in medical purposes and some in spacecraft objects.
 * This group has unusual atomic characteristics.

A common use for our element groups are to be in medical things and spacecraft objects. Another common use is in cancer therapy for patients.
