What Does PA Stand For?
PA stands for Pascal Protactinium
PA, or Pascal Protactinium, is a synthetic element with atomic number 91. Named after the renowned mathematician and physicist Blaise Pascal, it is part of the actinide series in the periodic table. Protactinium is notable for its role in nuclear chemistry and its potential applications in advanced reactors and scientific research. It is a dense, radioactive metal that can occur in small amounts in natural uranium ores. Due to its radioactivity and scarcity, PA is primarily of interest in specialized fields such as nuclear energy and materials science.
