MCQ
All the elements in a group in the periodic table have the same
- AAtomic number
- BElectronic configuration
- CAtomic weight
- ✓Number of electrons in the outermost shell or number of electrons for bonding
✓
Answer
Correct option: D.
Number of electrons in the outermost shell or number of electrons for bonding
d
Modern periodic table is compiled on the basis of atomic number of element. Hence, elements of each group or family have same number of electrons in their outermost or valence shell.
