Carbon forms four covalent bonds by sharing its four valence electrons...
Electronic configuration of carbon with atomic no. 6 = 2,4
The four valence electrons are involved in bonding with the four hydrogen atoms. Therefore after formation of four covalent bonds with hydrogen, atomic number of carbon in CH4 is 2+4+4 = 10, which is same as that of neon.

Carbon forms four covalent bonds by sharing its four valence electrons...
Carbon forms four covalent bonds by sharing its four valence electrons with four univalent atoms, such as hydrogen. In order to understand why the correct answer is option 'B' (neon), let's break down the electronic configuration of carbon before and after forming these bonds.
1. Electronic Configuration of Carbon:
Carbon has an atomic number of 6, meaning it has six electrons. The electronic configuration of carbon is 1s² 2s² 2p². In the outermost energy level (valence shell), carbon has four valence electrons in the 2s and 2p orbitals.
2. Formation of Covalent Bonds:
Carbon has the ability to form four covalent bonds because it can share its four valence electrons. In the case of hydrogen, each hydrogen atom has one valence electron in the 1s orbital. When carbon and hydrogen come together, carbon shares one electron from each of its four valence electrons with four hydrogen atoms. This results in the formation of four covalent bonds, with each bond consisting of a shared pair of electrons.
3. Electronic Configuration after Bond Formation:
After forming these four covalent bonds, carbon attains the electronic configuration of neon. Neon has an atomic number of 10 and an electronic configuration of 1s² 2s² 2p⁶. By sharing its four valence electrons, carbon now has a total of eight electrons in its valence shell, which matches the electronic configuration of neon.
In summary, carbon forms four covalent bonds by sharing its four valence electrons with four univalent atoms. This allows carbon to attain the electronic configuration of neon, represented by option 'B'. Carbon achieves a stable configuration by completing its valence shell with eight electrons, which is the same as the stable noble gas configuration of neon.
