Answer 1

在1898年英國的倫敦，Sir William Ramsay 和 Morris Travers 在液態空氣中發現了氖。他們在同年相繼發現氪、氖和氙，都是用相同的方法。

Sir William Ramsay is the key person in discovery of ALL NOBLE GASES. He was the professor of chemistry at the University of Bristol, England (1880–87), and at the University of London (1887–1913).

In 1984, Ramsay and Rayleigh discovered argon by devising a method that assured the total removal of nitrogen and oxygen from air. In 1985, Ramsay liberated helium from the mineral cleveite.

The positions of helium and argon in the periodic table indicated that at least 3 more noble gases should exist. In 1898 Ramsay and Morris W. Travers isolated these elements—called neon, krypton, and xenon—from air brought to a liquid state at low temperature and high pressure.

In 1910 Ramsay detected the presence of the last of the noble-gas series, called niton (now known as radon), in the radioactive emissions of radium.參考資料：http://www.britannica.com/eb/article-9062617/Sir-William-Ramsay
