An atom of sodium-23 (Na-23) has a net charge of + 1. identify the number of protons, neutrons, and electrons in the atom. How did you determine the number of each type. Explain in completer s details.

Answer 1:

Atomic number of sodium is 11. Atomic number signifies, number of electrons or protons present in the system. Since, atomic number of sodium is 11. Therefore, there are 11 protons present in the system.

Answer 2:

Atomic number of sodium is 11 and the atomic mass number of sodium is 23. The difference in atomic mass number and atomic number signifies, number of neutrons. In present case, number of neutrons = 23 - 11 = 12.

Answer 3:

Atomic number of sodium is 11. Atomic number signifies, number of electrons or protons present in the system. Since, atomic number of sodium is 11, the electrons present in the system is 11. But, the charge on sodium is + !. This suggest that, one electron is lost by sodium. Hence, number of electrons present in sodium ion is 10.

The correct number of neutrons is 12 while the number of protons is 11. That is because if the atomic number is 23, that means it's the isotope Na-23 and the atomic number is the sum of protons and neutrons. There are 11 protons as it can be seen on the periodic system. The number of electrons is 10 because it is positively charged, meaning that there's one electron fewer than the usual.
