An atom of sodium-23 (atomic number = 11) has a positive charge of +1. Given this information, how many

electrons does it have? How many protons and neutrons does this atom have?

neutral must have 11

so, the +1 ion has only 10 electrons

p+n = 23

p = atomic number

To determine the number of electrons, protons, and neutrons in an atom, we need to understand the structure of an atom. An atom consists of a positively charged nucleus at the center, which contains protons and neutrons, and negatively charged electrons that orbit around the nucleus.

Given that the atomic number of sodium-23 is 11, it tells us that there are 11 protons in the nucleus. Since the atom has a positive charge of +1, it means there is one fewer electron than the number of protons. Therefore, the number of electrons in an atom of sodium-23 is 10.

Now, to determine the number of neutrons, we subtract the number of protons (11) from the atomic mass (23). The atomic mass represents the total number of protons and neutrons in the nucleus. So, if sodium-23 has 11 protons, then it must have 23 - 11 = 12 neutrons.

In summary:
- Sodium-23 has 10 electrons.
- Sodium-23 has 11 protons.
- Sodium-23 has 12 neutrons.
