Question

Elements 104, 105, and 106 have been named rutherfordium (Rf), dubnium (Db), and seaborgium (Sg), respectively. These elements are synthesized from californium−249 by bombarding with carbon−12, nitrogen−15, and oxygen−18 nuclei, respectively. Four neutrons are formed in each reaction as well.

(b) Write the equations in shorthand notation. (For this part, omit all atomic numbers for the nuclides.)

Answer 1

Answer b):-

i) Fusion of Californium-249 isotope with Carbon -12 ions produces Rutherfordium-257 and four neutrons.

²⁴⁹Cf +  ¹²C    ²⁵⁷Rf  + 4 ¹n

ii) Fusion of Californium-259 isotope with Nitrogen-15 ion produces Dubnium-260 and four neutrons.

²⁴⁹Cf + ¹⁵N    ²⁶⁰Db + 4 ¹n

iii) Fusion of Californium-259 with the oxygen-18 ion produces Seaborgium-263 and four neutrons.

²⁴⁹ ​​​Cf  +  ¹⁸O ²⁶³Sg + 4 ¹n
