Question

Duplet and octet configuration differs in terms of:

• A. number of electrons in outermost shell
• B. number of electrons in innermost shell
• C. number of shells
• D. number of protons in outermost shell

Answer 1

Answer: (A), (C)

The correct options are
A number of electrons in outermost shell
C number of shells

Duplet and octet configuration differs in terms of:

1) Number of electrons in outermost shell: The atom of an element having duplet configuration has only two electrons in the outermost shell, whereas the atom of an element having octet configuration has 8 electrons in its outermost shell.

2) Number of shells: The atom of an element having duplet configuration has only 1 shell i.e. K-shell, whereas the atom of an element having octet configuration has more than 1 shell (K, L, M, N,.....).
