# Oxygen, carbon and hydrogen form how many bond (s) respectively?

- Now, considering oxygen atom the electronic configuration of oxygen with atomic number 8 will be $1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{4}}$ . Here, oxygen has a total of 6 valence electrons but to form stable octet structure, the oxygen gets a valency of two and the octet structure then satisfies.
- In case of carbon with atomic number 12 and electronic configuration $1{{s}^{2}}2{{s}^{2}}2{{p}^{2}}$, and it has outermost 4 electrons and need 4 more electrons to complete the octet structure and hence carbon forms 4 single covalent bonds and has the valency of 4.
- In case of hydrogen with atomic number 1 and configuration $1{{s}^{1}}$ has the capability to form only one covalent bond as it needs only one electron to fill its energy levels.
