Question
How many numbers of core electrons are there in the Ferrum?
- 24
- 26
- 25
- 27
Hint:
The number of core electrons in Fe is 24.
The correct answer is: 24
- The atomic number of Fe is 26.
- The core electrons are the electrons that are not valenced and do not take part in any bonding.
- The Fe has 2 valence electrons, so the number of core electrons is 24.
