1. How does carbon atom acquire stability? What is meant by tetravalency of carbon?
Answers
Valence Electrons in Carbon
Like other group 14 elements, carbon has four valence electrons. ... In a covalent bond, two atoms share a pair of electrons. By forming four covalent bonds, carbon shares four pairs of electrons, thus filling its outer energy level and achieving stability...
A carbon atom has four electrons in its outermost valence shell. So, it needs four more electrons to complete its octet. A carbon atom completes its octet only by sharing its valence electrons with other atoms. As a result, carbon atom forms four covalent bonds by sharing valence electrons with other atoms. This is known as tetravalency of carbon,(tetra means four). These four valences of carbon are directed towards four corners of a tetrahedron, and inclined to each other atomic an angle of a 109° 28´.
