Answer :
Final answer:
The atomic number of the nitrogen isotope with 8 neutrons and 10 electrons is 7, the mass number is 15, and it has a charge of -3.
Explanation:
To determine the atomic number, mass number, and charge for a nitrogen isotope with 8 neutrons and 10 electrons, we need to understand several concepts:
- The atomic number (Z) represents the number of protons in an atom and also determines the chemical identity of the element.
- The mass number (A) is the sum of the number of protons and neutrons in the nucleus of an atom.
- The charge of an atom is determined by the difference in the number of protons and electrons.
In the case of nitrogen, the atomic number of nitrogen is 7, which means it has 7 protons. Using the information provided that this nitrogen isotope has 8 neutrons, the mass number is the sum of protons and neutrons: 7 (protons) + 8 (neutrons) = 15. Lastly, the charge of the isotope can be found by subtracting the number of electrons from the number of protons: 7 (protons) - 10 (electrons) = -3.
So, the nitrogen isotope has a -3 charge.
Therefore, the atomic number is 7, the mass number is 15, and the charge is -3 for the nitrogen isotope in question.
