WebIn the 1890s, William Ramsay discovered an entirely new and unpredicted set of elements, the noble gases. After uncovering the first two, argon and helium, he quickly discovered three more elements after using the periodic system to predict their atomic weights. WebApr 8, 2024 · There are seven Noble Gas elements in the periodic table: helium, neon, argon, krypton, xenon, and radon. Noble Gasses are known as the least reactive Chemical elements. Noble Gasses are nearly inert because their atoms have an entire valence electron shell. So, they have a slight tendency to accept or donate electrons to form Chemical bonds.
