Problem: What are the differences in the compositions of the following pairs of atomic nuclei? 147N, 158OA) 158O has the same number of protons and the same number of neutrons as 147N. B) 158O has one more proton and one more neutron than 147N. C) 158O has one more proton and the same number of neutrons than 147N.

FREE Expert Solution

mass number = protons + neutrons

neutral atom: atomic number = # of protons = # of electrons

147N

• nitrogen
• atomic number = 7
• # of protons = # of electrons = 7
• mass number = 14
