Atomic bombs on Japanese cities

I'll appreciate anyone familiar with nuclear physics answering this
question.

Here is a quote from a newspaper article on the atomic bombing of Nagasaki:
"...delivered 10,000 pounds of Plutonium on the city." Is that figure
correct?

Thanks.

Nope, estimated size of the pit was 9 cm in diameter, and it weighed
6.2Kg - 13.5 pounds-ish. The whole FatMan BOMB weighed around 10,500 pounds

Yes: it included a great deal of high explosive, in a massive
spherical casing to direct the blast energy in a perfectly
symmetrical implosion, so as to crush the plutonium core to critical
density before the whole works disintegrated.

Unlike the "Little Boy" enriched-uranium bomb that struck Hiroshima,
the "Fat Man" design was so complex that it was deemed necessary to
test one before using it, even though at the time there was only
enough plutonium for two bombs (IIRC).

Yes, i read that the US pulled off a ruse with the Japanese.
Our intelligence led them to believe that we had a complete
nuclear arsenal, with several nukes just waiting to be
deployed.

And that's basically how V-J day (and the end of WWII)
came about...

happy days and...
starry starry nights!

No, That was the weight of the total bomb.
