What are the symbols for hydrogen and helium?
The symbol for hydrogen is H, and the symbol for helium is He.
Which is lighter - helium or hydrogen?
Helium is lighter than hydrogen. Helium has an atomic number of 2, which means it has two protons and two neutrons in its nucleus, making it lighter than hydrogen, which has only one proton in its nucleus.
What is the lighter element hydrogen or helium?
Hydrogen. It's first on the periodic table, with usually a sigle proton, and an atomic weight of 1.00794.
What does nuclear fusion convert hydrogen into?
Nuclear fusion converts hydrogen atoms into helium atoms. In the fusion process, hydrogen nuclei combine to form helium nuclei, releasing a large amount of energy in the form of heat and light.
Why is the amount of hydrogen in the sun decreasing?
The amount of hydrogen in the Sun is decreasing because nuclear fusion converts hydrogen into helium in the Sun's core. As the Sun converts hydrogen into helium, it gradually loses mass and energy, leading to a decrease in the hydrogen content over time. This process is part of the Sun's natural life cycle.
