<p>Plutonium - About 1940/41, meaning it would have been named after Pluto (before it was declassified as a planet)</p>

<p><code>Mercury</code> will be the Answer, Because <code>Mercury</code> is Very clear name with the 80th Element so planet is(However, Mercury was named after the <code>Roman God</code> which was related to what they called <code>quicksilver</code>).</p>

Plain wrong. For Uranium, Neptunium and Plutonium it's the other way around.

Can't you just take the nine (eight?) planet names and look for each in an alphabetic list of the elements?

This question appears to be off-topic because it shown no previous investigation AT ALL.

If you're going to count dwarf planets (Pluto/Plutonium), you should also count Cerium, which was named after Ceres (which was still classified as a planet when the element Cerium was named after it).
