Compared to 31P, the radioactive isotope 32P has
P-31 has 15 protons (atomic number = 15) and 16 neutrons in the nucleus and 15 electrons in the atom; 0 load
P-32 has 15 protons (atomic number = 15) and 17 neutrons in the nucleus and 15 electrons in the atom; 0 load
The answer will be -> d) plus a neutron
Question: if the mass number is equal to the number of protons + neutrons, how to know if the difference of the radioactive isotope 31p compared to the radioactive isotope 32p is the difference of protons or neutrons? The atomic number should be at the bottom left of the element. It is assumed to be the number of protons. If I don’t have the atomic number, how do I know if the difference between the two numbers is neutrons or protons?
d) one more neutron.
Both P-31 and P-32 have 15 protons, which is the atomic number of P. The different mass numbers are due to different numbers of neutrons. P-31 has 16 neutrons and P-32 has 17 neutrons.
There is one more electron
