Research Ready!
To do a proper investigation we need to get some back ground information. Usually detectives start with a date of birth and place. There are also things like unique characteristics, physical properties, weight and even uses that make an element different from the rest. Using the information and links below track down the answers you need for your Fugitive File to help create a better picture of the missing element.
A model of matterThe planetary model is the most familiar model or illustration of the structure of the atom. Since the ancient Greeks physicists agreed that the atom existed. However it was believed to be the smallest cohesive unit of matter until the experiments of J.J Thompson and later Rutherford B. Hayes in the early 20th century. The model gave modern physicists their current understanding of the atom and the particles that its composition consists of. The model is also known as the Hayes-Bohr model thanks to further research by the quantum physicist Neil Bohr.
as a matter of fact...Every good Wanted Poster has a picture on it! Since our fugitive element it sneaky lets make sure we include what most people see it as on the periodic table and its planetary model in our sketch. Use the research resources to help you create an accurate drawing.Click below to download the Suspect Sketch form, then print it and complete it to add to our Fugitive File.

Whats the Matter? Matter is everything around you. Matter is anything made of atoms and molecules. Matter is anything that has mass and takes up space. If you are new to the idea of mass, it is the amount of stuff in an object. View the video to the left to learn more about the states of matter.
Elements and compounds can move from one physical state to another and not change their basic atomic parts. Oxygen (O2) as a gas still has the same properties as liquid oxygen. The liquid state is colder and denser, but the molecules (the basic parts) are still the same. Water (H2O) is another example. A water molecule is made up of two hydrogen (H) atoms and one oxygen (O) atom. It has the same molecular structure whether it is a gas, liquid, or solid. Although its physical state may change, its chemical state remains the same. Laying the facts out on the table...The periodic table is considered by many to be the single most important chemistry reference available to scientists and researchers. It provides keys to understanding the building blocks our world is made of and has a seemingly unlimited amount of knowledge hidden in its columns, rows, letters and numbers.
