Just wondered since it is near the end of the chart.

No, its not true

Of course Plutonium is still considered an element. It has atomic no. 94 and was discovered, secretly, in 1940 by Glenn Seaborg with Wahl and Kennedy at Berkeley and publicly reported in 1946. Plutonium was extracted from uranium ore in 1947. Until recently the major use of plutonium has been for nuclear weaponry, it now finds its best use in deep space probe electricity sources. All 15 plutonium isotopes are radioactive, and most emit relatively weak alpha radiation which can be blocked even by a sheet of paper (but which is hazardous if within the body). Finally, in pure form plutonium exists in six allotropic forms or crystal structure - more than any other element.

LOL. That is a funny question. I think since plutonium atoms are so heavy, they should still be considered elements. Maybe we should demote some of the smaller ones to dwarf elements, at least the first three, anyway. Just because hydrogen was discovered a long time ago doesn't mean it is worthy.

Considering the revamped criteria for being in the Periodic Table of Elements, plutonium is no longer considered an element. It's now considered an "additive" and goes by the name "Mrs. Dash".

Of course it's an element. I don't really understand your question. Plutonium is just the name we give to the atom which has atomic number 94. It is and will forever be an element. It's not subjective.
EDIT:
Ok, I finally got the joke. I'm a bit slow on the uptake, but that was a pretty good one.

of direction this is. Plutonium and Neptunium are components that are dirived from Uranium (extremely Uranium 238). the two components have been got here upon in 1941 via 2 communities who weren't working jointly. the two communities desperate they might call their components simmularly to Uranium (Uranus) on account that Plutonium (Pluto) and Neptunium (Neptune) got here from Uranium. the actuality the Pluto isn't a planet anymore would not advise the element no longer exists.

Now that Pluto is not considered a planet, just a rock or something, Plutonium in now a non-element. Scientists have not come to this conclusion yet, but in time they will see things my way.

what? the only ones under review are the 100+ because some of the data is sketchy. plutonium is used in nuclear reactors so we know it's real therefore it's staying an element.

PLutonium is definitely an element. Manmade and the deadliest poison man has ever made.

Plutonium is an element.

It is a man-made, or synthetic element, meaning that it is not naturally occurring in/on the Earth, but it is still an element.
