To a first approximation, the Sun consists of a gas of equal numbers of protons and electrons. The temperature at the center of the Sun is about 10^7 K, and the density of the Sun is about 1x10^5 kg/m3. Because the temperature is so high, the protons and electrons are separate particles (rather than being joined together to form hydrogen atoms).
