The sun is best described as

The sun is described as a big star composed mainly of hot hydrogen and helium gas.

There are various layers in the Sun, including the core or core, the radiative zone, the convection zone, the photosphere (which emits most of the sunlight), the chromosphere and its outer part, the corona. Density decreases with altitude, from the nucleus to the atmosphere. The temperature in the nucleus is of the order of 15 million kelvin.

The solar atmosphere is a complex medium consisting of plasma subjected to an intense magnetic field, with solar flares and the solar wind. Sunspots, which appear dark because of their lower temperature, are, like the crown, radiosources. Solar activity related to these phenomena varies cyclically.

The observation of the solar spectrum is carried out thanks to spectroheliographs. This spectrum includes rays, known since Fraunhofer (1814), which signal the presence of hydrogen and helium mainly and about sixty other elements. It also includes bands that betray the presence of molecules in the solar atmosphere.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
