Answer
Noble gases, a section of the periodic table, owe their discovery to the contributions of Sir William Ramsay. Ramsay's meticulous research and experimentation led to the identification of helium, argon, neon, krypton, and xenon, elements that share a unique characteristic of chemical inertness. These gases, initially referred to as "inert gases," later came to be known as noble gases, a testament to their exceptional stability and low reactivity.
