How many electrons contain the ion that has 13 protons 10 electrons and 15 neutrons?
three, to make a total of 13
To determine the number of electrons in an ion, you need to consider its atomic number and charge. The atomic number of an element is equal to the number of protons it has. In this case, the given ion has 13 protons.
Since the ion is not specified to have any charge, we assume it is neutral. A neutral atom has the same number of protons and electrons. Therefore, the ion with 13 protons will also have 13 electrons.
However, you also mentioned that the ion has 10 electrons. This means that the ion has a positive charge because it has fewer electrons than protons. To find the charge on the ion, you subtract the number of electrons from the number of protons. In this case, 13 protons minus 10 electrons equals a positive charge of +3.
So, the ion that has 13 protons, 10 electrons, and 15 neutrons has 10 electrons if it is positively charged, but it would have 13 electrons if it is neutral.
