What element did Sir William Ramsay discover in 1898?
While seeking sources of argon in the mineral kingdom, Ramsay discovered helium in 1895. Guided by theoretical considerations founded on Mendeleev’s periodic system, he then methodically sought the missing links in the new group of elements and found neon, krypton, and xenon (1898).
What did Sir William Ramsay and Lord Rayleigh discover on the periodic table?
In the mid 1800s, Mendeleev created the periodic table, but there were still a few problems with it. William Ramsay discovered one of these issues: he found that it was missing an entire group, the group of noble gases. Working with Lord Rayleigh, he first discovered argon and then helium.
Who discovered group 0?
Dmitri Mendeleev
In 1902, having accepted the evidence for the elements helium and argon, Dmitri Mendeleev included these noble gases as group 0 in his arrangement of the elements, which would later become the periodic table.
What kind of gases did Sir William Ramsay discover?
See Article History Sir William Ramsay, (born Oct. 2, 1852, Glasgow, Scot.—died July 23, 1916, High Wycombe, Buckinghamshire, Eng.), British physical chemist who discovered four gases (neon, argon, krypton, xenon) and showed that they (with helium and radon) formed an entire family of new elements, the noble gases.
What did William Ramsay discover in High Wycombe?

How did Ramsay contribute to the periodic table?
In his book The Gases of the Atmosphere (1896), Ramsay showed that the positions of helium and argon in the periodic table of elements indicated that at least three more noble gases might exist.
