Sun does not have a definite boundary, and the density of the outer parts decreases exponentially with increasing distance from its center.
The core is the only region that produces appreciable amount of energy through fusion. Remainder of the sun is heated by this energy as is transferred outward through many successive layers, escaping finally though photosphere.
Apart from heat and light, sun also emits a stream of charged particles called the solar wind.
The sun is mostly made up of two gases, 74% hydrogen and 24% helium. Oxygen, carbon, iron, and neon make up the remaining percentage.
