how many proton and electrons does Fe+2 have?
26 protons 26 electrons
26 protons 28 electrons
26 protons 24 electrons
24 protons 26 electrons
Protons= atomic #
Electrons= the atomic # +/- charge (if its a positive charge u minus if its a negative charge u plus)
To determine the number of protons and electrons in an ion, you need to know the atomic number and the charge of the ion.
In this case, you're given the ion Fe+2, which means it has a charge of +2.
The atomic number of iron (Fe) is 26, which indicates that there are 26 protons in the nucleus of an iron atom.
To determine the number of electrons in the Fe+2 ion, you need to remember that ions are formed when atoms gain or lose electrons.
Since Fe+2 has a positive charge of +2, it means that it has lost two electrons.
Thus, to find the total number of electrons, you subtract 2 from the atomic number of iron (26).
Therefore, Fe+2 has 26 protons and 24 electrons.
So, the correct answer is: 26 protons and 24 electrons.
