whats the sun made up of?

Mostly Hydrogen.\n\nAt the center of the Sun, where its density reaches up to 150,000 kg/m3 (150 times the density of water on Earth), thermonuclear reactions (nuclear fusion) convert hydrogen into helium, releasing the energy that keeps the Sun in a state of equilibrium. About 8.9 ×1037 protons (hydrogen nuclei) are converted into helium nuclei every second, releasing energy at the matter-energy conversion rate of 4.26 million tonnes per second, 383 yottawatts (383 ×1024 W) or 9.15 ×1010 megatons of TNT per second. The fusion rate in the core is in a self-correcting equilibrium: a slightly higher rate of fusion would cause the core to heat up more and expand slightly against the weight of the outer layers, reducing the fusion rate and correcting the perturbation; and a slightly lower rate would cause the core to shrink slightly, increasing the fusion rate and again reverting it to its present level.\n\nHydrogen 92.1%\nHelium 7.8%\nOxygen 0.061%\nCarbon 0.030%\nNitrogen 0.0084% \nNeon o.0076%\nIron 0.0037%\nSilicon 0.0031%\nMagnesium 0.0024%\nSulfur 0.0015%

These particles include atomic constituents such as electrons, protons, and neutrons (protons and neutrons are actually composite particles, made up of quarks), as well as other particles such as photons and neutrinos which are produced copiously in the sun. However, most of the particles that have been discovered and studied are not encountered under normal earth conditions; they are produced in cosmic rays and during scattering processes in particle accelerators.

The Sun is the only "substance" that can produce solar power!\n\nDid you perhaps mean what chemical substances can harness solar power?  Most solar cells are made from semi-conducting materials like Silicon and Germanium.  \n\nHere's some info:

The sun’s history \n\n5 billion years ago, a small cloud of gas and dust began to compress under its own weight, or if your a creationist 5000 years ago. As more and more gas began to be crushed on the weight of gravity, hydrogen within the core began to fuse together. This fusion processes, one still sought by earth's scientist makes hydrogen into helium, and release’s incredible amounts of energy. This energy is converted into tremendous amounts of heat and light, which forms the energy source for our planet. Imagine the power you could amass if you were able to corner the market on the amount of sunlight hitting the earth. The cloud from which the sun is formed, fortunately for us, did not use all of its gas and dust to make the Sun; that which was left over, less than one percent of the original material, formed the 9 planets. Incidentally Jupiter could be considered a failed sun, that didn't have sufficient mass to start the fusion process. \n\nLuckily for us in the real estate business the sun has 3 to 4 billion years more of prime building time. As the sun begins to age more and more of its interior will be converted into helium. Once the sun exhausts its source of fuel, it will begin fusing helium into heavier elements. The heaver element carbon, the primary new fusion product, gives off a lot more energy than the similar production of helium. This excess energy will make your property on the sun even more valuable, since the excess energy could be harvest for your use. In fact as the sun pumps out more energy it cause the outer layer of the sun to expand and will engulf the inner core planets up to Mars. This lost of prime real estate will make your investment in the sun even more valuable, since the available area for building will be reduced. Not to mention but the sun's color will change to a pleasing Red color, a nice change of pace from the current yellow/orange hue our sun currently has. .

It absorbs light energy from the sun.

It's going to be difficult to tell you more than I know, but I'll give it my best shot.\n\nThe sun is big and bright and hot.  It is a giant fusion reactor creating energy by fusing atoms of matter together.  The energy is transmitted out into space as photons of light.\n\nIt is a medium sized yellow star which began making energy about 4 billion years ago and is estimated to have about 5 billion years left before its fuel begins to run out.

The sun is largely hydrogen & helium, with a bit of iron & other elements.  The fraction of the sun that's oxygen, however, is minuscule, so you just wouldn't get any appreciable chemical burning.  In order for your question to make any sense or to be possible at all, you'd need to state the chemical composition of the sun and say what percent is oxygen in your hypothetical question.

The energy from the sun comes from nuclear fussion: the combining of 2 Hydrogen atoms to make Helium and energy.\nWhen the sun will lose it's fuel (in about 5 Billion years), it will turn into a red giant star.

Mostly hydrogen. There is a little bit of helium and heavier elements in there as well.

The Sun's outer visible layer is called the photosphere and has a temperature of 6,000°C (11,000°F). This layer has a mottled appearance due to the turbulent eruptions of energy at the surface. \n\nSolar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place.

The sun operates like all other stars in it uses fusion to create its energy.  The sun is made of hydrogen and when a hydrogen molecule is combined with an oxygen molecule at a highspeed it becomes helium and the excess energy from the two molecules combining gives the sun its heat.  Gravity is working to crush the star and its fusion energy is working to inflate it.  This is what gives the star its spherical shape.

what is the atom made of and explain how they work?

Sunlight is made up of all the colors of the rainbow: red, orange, yellow, green, blue, and violet. Some of the sunlight is reflected off the surface of the water, reflecting the color of the sky. Some of the sunlight penetrates the water and is scattered by ripples and particles in the water (this tinges the appearance of the ocean with the color of the particles). In deep water, much of the sunlight is scattered by the oxygen in the water, and this scatters more of the blue light.

The Sun is roughly 100 times the diameter of Earth, which is about one million times the volume.

The heat and light in the sun is due to the vast amounts of energy produced at the core. At the core hdrogen atoms combine together to form Helium atoms due to the pressure (billions of atmospheres.) and temperature (15 million degrees C). This reaction is called fusion. \n\n  However the mass of the helium atoms produced is slightly less than the combining hydrogen atoms. This difference in the mass is coverted into energy according to einsteins equation E= mc2 (c is squared).\n  This energy is in the formed of gamma rays which reaches the earth. However what we look at is only the surface of the sun called the "photosphere" which is very much cooled than the core (just 6000 degrees).\n\nThe sun wont always be bright. Eventually as the hydrongen gets used up, the reaction will slow down and the sun will become a red giant and on further reduction will become a white dwarf and at the end it will be a black dwarf.

Clouds are made up of water vapour which rise into the air by the heat of the sun. They stay at a height where the sun has just enough effect to keep them up.
