The correct table is:
Particle Number
protons 31
neutrons 39
electrons 28
The atomic number of an atom is equal to the number of protons. The mass number, which is the total number of protons and neutrons, minus the number of protons gives the number of neutrons. For a charged ion, the number of electrons is not equal to the number of protons. In this case, Gallium (Ga) has a charge of +3, meaning it has lost 3 electrons, hence it has 28 electrons.
Gallium has an atomic number of 31 and a mass number of 70. Which table shows the number of protons, neutrons, and electrons in a gallium ion with a +3 charge?(1 point)ResponsesParticle Numberprotons 31neutrons 39electrons 28Particle Number protons 31 neutrons 39 electrons 28Particle Numberprotons 31neutrons 39electrons 31Particle Number protons 31 neutrons 39 electrons 31Particle Numberprotons 39neutrons 31electrons 39Particle Number protons 39 neutrons 31 electrons 39Particle Numberprotons 39neutrons 31electrons 36
