Question

what are the elements is synthesized when 15 neutrons strike the nucleus of Ura nium-238, emitting 7 beta particles ?

Answer 1

Answer:

Plutonium is the element with the highest atomic number to occur in nature. Trace quantities arise in natural uranium-238 deposits when uranium-238 captures neutrons emitted by decay of other uranium-238 atoms.

Density (near r.t.): 19.85 (239Pu) g/cm3

Natural occurrence: from decay

Atomic number (Z): 94

Atomic radius: empirical: 159 pm
