The correct Answer is:
To determine which atom can have more than eight valence electrons when forming covalent bonds, we need to analyze the electronic configurations of the given atoms: hydrogen, nitrogen, fluorine, and chlorine. ### Step-by-Step Solution: 1. **Understanding Hypervalency**: - An atom is considered hypervalent if it can have more than eight electrons in its valence shell when forming covalent bonds. This typically occurs in elements from the third period and beyond, as they have available d-orbitals. 2. **Analyzing Hydrogen**: - **Electronic Configuration**: Hydrogen (H) has the electronic configuration of 1s¹. - **Valence Electrons**: It has only 1 valence electron and no vacant d-orbitals. - **Conclusion**: Hydrogen cannot be hypervalent. 3. **Analyzing Nitrogen**: - **Electronic Configuration**: Nitrogen (N) has the electronic configuration of 1s² 2s² 2p³. - **Valence Electrons**: It has 5 valence electrons and no vacant d-orbitals. - **Conclusion**: Nitrogen cannot be hypervalent. 4. **Analyzing Fluorine**: - **Electronic Configuration**: Fluorine (F) has the electronic configuration of 1s² 2s² 2p⁵. - **Valence Electrons**: It has 7 valence electrons and no vacant d-orbitals. - **Conclusion**: Fluorine cannot be hypervalent. 5. **Analyzing Chlorine**: - **Electronic Configuration**: Chlorine (Cl) has the electronic configuration of 1s² 2s² 2p⁶ 3s² 3p⁵. - **Valence Electrons**: It has 7 valence electrons but also has vacant 3d orbitals. - **Conclusion**: Chlorine can utilize these vacant d-orbitals to accommodate more than 8 valence electrons, making it a hypervalent atom. 6. **Final Answer**: - Among the given options, chlorine is the atom that can have more than eight valence electrons when forming covalent bonds. ### Answer: **Chlorine (Cl)** can have more than eight valence electrons when forming covalent bonds.

How is covalent bond formed ?

Ionic bond is defined as the electrostatic force of attraction holding the oppositely charged ions. Ionic compounds are mostly crystalline solid having high melting and boiling points, electrical conductivity in moleten state, solubility in water etc. Covalent bond is defined as the force which binds atoms of same or different elements by mutual sharing of electrons in a covalent bond. Covalent compounds are solids, liquids or gases. They have low melting and boiling points compounds. They are more soluble in non-polar solvents. The valence electrons are involved in formation of covalent bonds is /are called :

    Oxygen differs from the other elements of the group. Compounds of oxygen with metals are more ionic in nature and hydrogen bonding is more important for oxygen compounds. Oxygen is never more than divalent beacasue when it hs formed two covalent bonds, there are no low energy orbitals which can be used for form. further bonds. However, the elements S,Se,Te and Po have empty d- orbitals which may be used for bonding, and they can form four or six bonds by unpairing electrons. The higher oxidation states become less stable on decending the group. The bond between S and O, or Se and O, are much shorter than might be expected for a single bond owing to rho pi - dpi interaction between the p- orbital of oxygen and d- orbital of S or Se. Which of the following statemet is incorrect ?

    What happens to the potential energy of the system when two atoms form a covalent bond?

    Diamond is hard because all the four valence electrons are bonded to four carbon atoms by comvlent bonds .

    Assertion : The atoms in a covalent molecule are said to share electrons, yet some covalent molecule are polar. Reason :In a polar covalent molecule , the shared electron spend more time on the average near one of the atoms .
