Big Bang nucleosynthesis refers to the process that occurred within the first few minutes of the universe's existence, leading to the formation of the lightest elements such as hydrogen, helium, and small amounts of lithium and beryllium. This process provides critical evidence for the Big Bang theory and helps explain the observed abundance of light elements in the universe today.

hydrogen

Helium is a noble gas with the atomic number 2, known for its low density and inertness, making it invaluable in applications requiring non-reactive environments, such as in cryogenics and as a protective gas in welding. Its scarcity on Earth, primarily extracted from natural gas reserves, underscores its importance and the need for sustainable management of its resources.
