Li7

Li-7, also known as lithium-7, is a stable isotope of lithium with a mass number of 7. It is the only stable isotope of lithium, making up approximately 92.5% of naturally occurring lithium. The nucleus of Li-7 consists of 3 protons and 4 neutrons.

Lithium-7 is primarily used in the production of tritium, which is a key component in nuclear fusion

Li-7 is also used in various applications, including as a coolant in some types of nuclear reactors

Lithium-7 has a natural abundance of approximately 92.5%, with the remaining 7.5% consisting of the isotope Li-6.
