Fuel elements for PWR and BWR are described here (from Wikipedia) There is a picture shown but pictures don't reproduce on Wikianswers.
Pressurized water reactor (PWR) fuel consists of cylindrical rods put into bundles. A uranium oxide ceramic is formed into pellets and inserted into Zircaloy tubes that are bundled together. The Zircaloy tubes are about 1 cm in diameter, and the fuel cladding gap is filled with helium gas to improve the conduction of heat from the fuel to the cladding. There are about 179-264 fuel rods per fuel bundle and about 121 to 193 fuel bundles are loaded into a reactor core. Generally, the fuel bundles consist of fuel rods bundled 14x14 to 17x17. PWR fuel bundles are about 4 meters in length. In PWR fuel bundles, control rods are inserted through the top directly into the fuel bundle. The fuel bundles usually are enriched several percent in 235U. The uranium oxide is dried before inserting into the tubes to try to eliminate moisture in the ceramic fuel that can lead to corrosion and hydrogen embrittlement. The Zircaloy tubes are pressurized with helium to try to minimize pellet cladding interaction (PCI) which can lead to fuel rod failure over long periods. In boiling water reactors (BWR), the fuel is similar to PWR fuel except that the bundles are "canned"; that is, there is a thin tube surrounding each bundle. This is primarily done to prevent local density variations from effecting neutronics and thermal hydraulics of the nuclear core on a global scale. In modern BWR fuel bundles, there are either 91, 92, or 96 fuel rods per assembly depending on the manufacturer. A range between 368 assemblies for the smallest and 800 assemblies for the largest U.S. BWR forms the reactor core. Each BWR fuel rod is back filled with helium to a pressure of about three atmospheres (300 kPa).
An atomic number or any other nuimber is just a number and you can't draw it, apart from your own imagination of it.
show me a picture of a element
A pixel is short for picture element.
I need a picture of a nucleus can i please get a picture of a nucleus
what is a picture of an opposite ray? what is a picture of an opposite ray?
Element #105 is an artificial element, and it is called Dubnium.
A Pixel is a picture element. (pix + el...) It may be of any dimension suited to the use. The CRT screen in front of me is only a few million pixels, but is adequate for the purpose. A nanometre is 10-9 of a metre.

I don't think it has a picture because it has something to do with air around us.

The word "pixel" is itself a contraction of the words "picture element", the smallest individual part of a display image. (see related question)
The word pixel was derived from 'picture element'. Pix is a popular short form for picture and el is the start of element.
There are photos of this element in wikipedia.
