Question

Balance the nuclear reactions given below by placing the correct mass number or atomic symbol in the box provided. If you don't know the atomic numbers or symbols of nuclei, you can find a simple periodic table of the elements online at http://www.webelements.com/ 120 + 12C + 20 Ne + 4He You are correct. Submissions to practice problems are not permanently recorded. Previous Tries 13C + 14N → 22 Ne + 4He + 1 H You are correct. Submissions to practice problems are not permanently recorded. Previous Tries For this part of the problem you will have to identify both the mass number and the atomic number (and symbol) for the missing nuclear reaction product. Note that a proton (p) is the same as 1h for purposes of balancing this equation and the "n" is a neutron. p + 180 + Submit Answer + 4He + n Tries 0/999

Answer 1

Proton (same as ļH) pt Dot" He tn. Let the Atomic number be y and mass number be Mass number of the left hand - 18+1=19 and mais number be ful So to mars number on the Right hand should also be 19. - 19= x+y+1 = x= 19-5=1141 Oxygen's abomic number the left Hand= 8+1=9 Atomic number on add up to So abonic number on the right hand should 9. & Helium's atomic number So 9 = y + 2 to . So y=17 The element with atomic number 7 is NO So the missing nuclear product is liun!
