Carbon forms four covalent bonds by sharing its four valence electrons with four univalent atoms, e.g., hydrogen. After the formation of four bonds, carbon attains the electronic configuration of

Options

A. helium
B. neon
C. argon
D. krypton

Answer

B

Explanation

Electronic configuration of carbon (C ) = 2, 4 when it forms four covalent bonds by sharing its four valence electrons with hydrogen, it forms `CH_(4)` molecule like this

Now, electronic configuration of C in `CH_(4)` =2, 8
Atomic number of Ne is 10. Its electronic configuration is `underset(2,)K" "underset(8)L`
Theresore, after the formation of four bonds, carbon attains the electronic configuration of neon.
