None of the reactions given include a beta decay, so the number of protons, the number of
neutrons, and the number of electrons are each conserved. Atomic numbers (numbers of protons
and numbers of electrons) and molar masses (combined numbers of protons and neutrons) can
be found in Appendix F of the text.
(a) 1H has 1 proton, 1 electron, and 0 neutrons and 9Be has 4 protons, 4 electrons, and 9¡4 = 5
neutrons, so X has 1 + 4 = 5 protons, 1 + 4 = 5 electrons, and 0 + 5 ¡ 1 = 4 neutrons. One of
the neutrons is freed in the reaction. X must be boron with a molar mass of 5 g=mol + 4 g=mol =
9 g=mol: 9B.
(b) 12C has 6 protons, 6 electrons, and 12 ¡6 = 6 neutrons and 1H has 1 proton, 1 electron, and
0 neutrons, so X has 6 + 1 = 7 protons, 6 + 1 = 7 electrons, and 6 + 0 = 6 neutrons. It must be
nitrogen with a molar mass of 7 g=mol + 6 g=mol = 13 g=mol: 13N.
(c) 15N has 7 protons, 7 electrons, and 15 ¡ 7 = 8 neutrons; 1H has 1 proton, 1 electron, and 0
neutrons; and 4He has 2 protons, 2 electrons, and 4 ¡ 2 = 2 neutrons; so X has 7 + 1 ¡ 2 = 6
protons, 6 electrons, and 8 + 0 ¡ 2 = 6 neutrons. It must be carbon with a molar mass of
6 g=mol + 6 g=mol = 12 g=mol: 12C.
