Complete the following nuclear equations. 13. 3K e + 16. 339 Pu → He + alt 14. Be + Be + 8y 17. $U → + 231 Th 15. Li → He + 18. 23491 Pa → + 23492 U Nuclear Decay Series The figure maps the radioactive decay of uranium-238 to lead-206. Use the figure to answe the following questions. By B,Y 19.How many alpha particles are - 2 24 produced as one atom of uraniu

Answer 1

MK - ģe + - 5 The number written in superscript shows mass mmber mais number = Atomic numbes + A number of neutrons, Neumber written in suborript is Atomic numbes In this decay, a figpe of prminus decay an energetic negative electron as emitted, so in product ride, considering atomie mmber. 1934't me uz 20. 9д + rays are protons mass or charige Полите с и).

& Li the + = It is a type of alphe decay , and an . alpha particle (the) is released. . So the product element will have man number of 2 and atomie no.l... Fon mans no. 6 = 4 tu .: U = 2 Por atanie no. 3=2tu 0-) so. Gli - a the + ?H . 9 239 eu. - the + - 94 for decrease in mans no. of new element 239 = 4 tu j e i - 235 for decrease in atomic number n new element - qua 2 tu .. na 92. So, 239 Pu - the at 235 qu' - ©. 2,35 . . . + Th.

Uranium losses 2 neutrons 2 protons This is an alpha decay. atomie and - 235 125... 929 © 234 Pa - - + mu 91 There is no change in mass no. no: - we will look tos atomie number 9l u 792 are so the decayed vммо афсил 2 234 Pa particle has to щ». м 0 или _о. - u dua de + 234 Az
