* Hydrogen (H): This makes up about 70.6% of the Sun's mass.

* Helium (He): This makes up about 27.4% of the Sun's mass.

These gases are present in a plasma state, meaning they are superheated and ionized, with electrons stripped from the atoms.

While hydrogen and helium dominate the Sun's composition, trace amounts of other elements are also present, including:

* Oxygen (O)

* Carbon (C)

* Neon (Ne)

* Iron (Fe)

* Silicon (Si)

* Magnesium (Mg)

* Sulfur (S)

* Nickel (Ni)

* Calcium (Ca)

These trace elements are much less abundant than hydrogen and helium, but they still play a crucial role in the Sun's internal processes and energy production.
