A star is a big mass of hot gases that has enough mass to achieve stellar ignition. A star usually at it's birth has 90 percent hydrogen, 10 percent helium, it can't have more than 1 percent of heavier elements. It burns through a process called nuclear fusion where lighter elements with a smaller amount of protons such has hydrogen fuse together to. If two hydrogen atoms fuse together, they each have one proton, they fuse and now, their is two protons which means, it has turned into helium, two helium atoms can fuse and turn to heavier elements. After all gases are turned to elements like iron, the star will reach the end of it's life cycle and grow ten times bigger than it's original size. If it was a big star, it is now classed has a red super giant, if it was a small star, it is now classed has a red giant. From here on, if it is huge, it can explode into a hyper nova and turn into a black hole or neutron star. When a smaller star dies, it explodes in a supernova. It will be turned into a dwarf star and it's last light will die out after words. After it ignites, it's life span depends on how big it is, if it is a huge star, it will fuse it's gas source faster into heavier elements and die out quicker, if it is smaller, even though it will have less gases, it will burn them slower and live longer. Through it's life, it goes through a number of colors based on how long it has left to live.
Blue Youngest 50,000-25,000 degrees Celsius
Blueish White 24,999-10,000 degrees Celsius
White 9,999-7,500 degrees Celsius
Yellow 7,499-5,000 degrees Celsius
Orange 4,999-3,500 degrees Celsius
Red 3,499-2,500 degrees Celsius

The Sun is predominantly made of hydrogen and helium. Other substances exist in minimal amounts. Hydrogen accounts for about 73% and Helium for about 25%. The rest 2% is a mixture of other substances, including oxygen, carbon, sulfur, iron, etc.

Spectroscopy shows that hydrogen makes up about 94% of the solar material, helium makes up about 6% of the Sun, and all the other elements make up just 0.13% (with oxygen, carbon, and nitrogen the three most abundant ``metals''---they make up 0.11%). In astronomy, any atom heavier than helium is called a ``metal'' atom. The Sun also has traces of neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, potassium, and iron. The percentages quoted here are by the relative number of atoms. If you use the percentage by mass, you find that hydrogen makes up 78.5% of the Sun's mass, helium 19.7%, oxygen 0.86%, carbon 0.4%, iron 0.14%, and the other elements are 0.54%.

sun is just a ball of gas.it mainly contains helium and hydrogen.the hydrogen fuse to produce helium .

Mostly hydrogen, a little bit of helium and traces amounts of other elements all in plasma state.

It's a ball of burning gas, hydrogen and some gases.
