P9+-+Actinides

The Actinides themselves make up element number 89 on the list, and elements 89-103 are each of the following Actinides.
 * Actinides are chemically similar elements that are radioactive gases and contain multiple elements of the periodic table starting with the element 89. This is also the atomic number. These elements are highly t__oxic!__

Actinides: 89-Actinium-Ac 90- Thorium-Th 91- Protactinium-Pa 92- Uranium-U 93- Neptunium-Np 94- Plutonium-Pu 95- Americium-Am 96- Curium-Cm 97- Berkelium-Bk 98- Californium-Cf 99- Einsteinium-Es 100- Fermium-Fm 101- Mendelevium-Md 102- Nobelium-No 103- Lawrencium-Lr

Uses: Some common uses are being displayed in bombs and weapons as well as in medical studies.**

Actinides start in Group 7 (vertical), Period 4 (horizontal) and end with Lawrencium at Group 7, Period 3
 * Chemical Properties:**
 * **Actinides are solids at room temperatures.**
 * **Actinides combine directly with most nonmetals.**
 * **These elements are not flammable.**
 * **They react with boiling water at 212oF.**


 * Physical Properties:**
 * **They are electropositive.**
 * **They are radioactive.**
 * **Some of their freezable temperatures are very low.**


 * Some cool facts are....**
 * The word "Actinide" came from the Greek word "ray" which was short for "radio active".
 * Thorium and Uranium are two and the only Actinides that we've found in the earth's crust
 * We have also found Plutonium and Neptunium in traces of Uranium Ores as a result of decay or bombardment.
