With which scientist did William Ramsay show in 1894 that air also contained an element unknown till then, which was named argon?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Lord Rayleigh.
In 1894, William Ramsay collaborated with the scientist Lord Rayleigh (John William Strutt) to demonstrate that air contained an element unknown until then, which was subsequently named argon. Lord Rayleigh had discovered that the density of nitrogen extracted from air was different from that of nitrogen obtained from chemical compounds. Ramsay, through further experiments, isolated argon, a noble gas, confirming its presence in the atmosphere and expanding the understanding of atmospheric composition.
