Fe has 26 protons in its nucleus. What are the number of electrons in Fe
2+
(II) ion?
- A24
- B26
- C28
- D13
Solution & Step-by-step Explanation
A neutral Iron atom (Fe) has an atomic number of 26, which means it contains 26 protons and 26 electrons.
When it forms an Fe
2+
ion, it loses 2 electrons from its outermost shell.
Therefore, the number of electrons in the Fe
2+
ion is:
26−2=24
When it forms an Fe
2+
ion, it loses 2 electrons from its outermost shell.
Therefore, the number of electrons in the Fe
2+
ion is:
26−2=24
