How many protons,neutrons,and electrons are in a silver atom with a mass number of 108?

Question

Quizplus · Accepted Answer

The mass number of an atom is the sum of its protons and neutrons in the nucleus. In this case, the mass number is given as 108. Therefore, the number of protons and neutrons combined is 108.

The atomic number of an atom is the number of protons in its nucleus. The atomic number for silver is 47. Therefore, the number of protons in this silver atom is 47.

To find the number of neutrons, we subtract the number of protons (47) from the mass number (108), giving us 61 neutrons.

Finally, to find the number of electrons, we must consider the charge of the atom. Since silver has an atomic number of 47, it is neutral and has an equal number of electrons as protons. Therefore, this silver atom also has 47 electrons.

Putting all of this together, we get B) 47 protons, 61 neutrons, 47 electrons as the correct answer.
