The correct answer is C. More helium and less hydrogen
Explanation:
The Sun, which is the center of the solar system, is mainly composed of two gases: hydrogen and helium. Additionally, every second and through nuclear fusion the hydrogen is fused and this creates helium, which is a heavier element. This implies as the sun ages the amount of hydrogen will decrease as the amount of helium increases, as a result of constant nuclear fusion. Indeed, right now helium exists in a lower quantity than hydrogen, but every second, minute, hour, etc. the amount of helium increases, and it is expected in millions of years there is more helium than hydrogen.
You don't have an answer choice.
Everything that has a temperature gives off electromagnetic radiation (light). Shortwave radiation contains higher amounts of energy and longwave radiation contains a smaller amount of energy. Therefore, the sun gives off shortwave radiation, as it is extremely hot and has a lot of energy to give.
The columns on the periodic table are called groups or families. The elements in the same group have similar properties. One of these particles is electrons.
