Answer: (b)
It is a fundamental atomic system composed of a bound electron and its antimatter counterpart, a positron.
Positronium is a unique atomic system comprising a bound electron and its antimatter equivalent, a positron. Unlike hydrogen, which consists of a proton and an electron, positronium contains a positively charged positron and a negatively charged electron. It was first detected by scientists in the United States in 1951. Despite its fundamental significance, positronium has a very short life, with a half-life of only 142 nanoseconds, after which it annihilates. Positronium’s mass is twice that of an electron, and it is considered a pure leptonic atom.
