ETIMOLOGIA DELLA PAROLA PLUTONIUM
Named after the dwarf planet Pluto because Pluto lies beyond Neptune and plutonium was discovered soon after neptunium.
CHE SIGNIFICA PLUTONIUM IN INGLESE
Plutonio
Il plutonio è un elemento chimico radioattivo transuranico con il simbolo Pu e il numero atomico 94. È un metallo di attinide di aspetto grigio-argenteo che si accarezza quando è esposto all'aria e forma un vernice opaco quando viene ossidato. L'elemento presenta normalmente sei allotropi e quattro stati di ossidazione. Reagisce con carbonio, alogeni, azoto, silicio e idrogeno. Quando esposto ad aria umida, forma ossidi e idruri che espandono il campione fino al 70% in volume, che a sua volta sciacquano come una polvere che può ignorare spontaneamente. È radioattivo e può accumularsi nelle ossa. Queste proprietà rendono pericoloso il trattamento del plutonio. Il plutonio è l'elemento primordiale più pesante in virtù dell'isotopo più stabile, plutonio-244, la cui metà di vita è di circa 80 milioni di anni è sufficiente per l'elemento di essere trovato in quantità di traccia in natura. Plutonio è per lo più un sottoprodotto di reazioni nucleari nei reattori in cui alcuni dei neutroni liberati dal processo di fissione trasformano nuclei uranio-238 in plutonio.
definizione di plutonium nel dizionario inglese
La definizione di plutonio nel dizionario è un elemento transuranico metallico altamente tossico. Si presenta in tracce di minerali di uranio e viene prodotto in un reattore nucleare mediante bombardamento di neutroni dell'uranio-238. L'isotopo più stabile e importante, il plutonio-239, subisce prontamente la fissione e viene usato come combustibile per reattori nelle centrali nucleari e nelle armi nucleari. Simbolo: Pu; numero atomico: 94; emivita di 239Pu: 24 360 anni; valenza: 3, 4, 5 o 6; densità relativa: 19,84; punto di fusione: 640 ° C; punto di ebollizione: 3230 ° C.

5 CITAZIONI IN INGLESE CON «PLUTONIUM»
Citazioni e frasi famose con la parola
plutonium.
Once we open the door to the plutonium economy, we expose ourselves to absolutely terrible, horrifying risks from these people.
There are many different kinds of radioactive waste and each has its own half-life so, just to be on the safe side and to simplify matters, I base my calculations on the worst one and that's plutonium.
For 50 years, nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium, lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task, and most of the cost, of making safe sites that have been polluted half-way to eternity.
Every actor looks all his life for a part that will combine his talents with his personality... 'The Odd Couple' was mine. That was the plutonium I needed. It all started happening after that.
My job was to produce plutonium that was used for atomic bomb.
