Question
In an atom the electrons other than the valence electrons are called
- Core electrons
- Inner electrons
- Valence electrons
- Both A and B
Hint:
The electrons of an atom other than the valence electrons are core electrons or inner electrons.
The correct answer is: Both A and B
- The electrons in atoms are distributed around the nucleus with a fixed amount of energy.
- The electrons around the nucleus are distributed in shells or orbits.
- The electrons of the outermost shell are called valence electrons which are responsible for the reactivity of the atom
- The electrons other than the valence electrons are called core electrons or inner electrons as they lie on the inner shells of orbits.
