Answer 2

Electron Configuration of Hydrogen (H) and Chlorine (Cl) Atoms

To determine the electron configuration of hydrogen (H) and chlorine (Cl) atoms, we can refer to the periodic table. Hydrogen has an atomic number of 1, indicating that it has one electron. The electron configuration of hydrogen is 1s^1.

Chlorine, on the other hand, has an atomic number of 17, indicating that it has 17 electrons. The electron configuration of chlorine is 1s^2 2s^2 2p^6 3s^2 3p^5.

Formation of Hydrogen Chloride (HCl) Molecule

The hydrogen chloride (HCl) molecule is formed through the sharing of electrons between hydrogen and chlorine atoms. Hydrogen has one valence electron, while chlorine has seven valence electrons.

In the formation of the HCl molecule, the hydrogen atom shares its single electron with the chlorine atom. This sharing of electrons allows both atoms to achieve a more stable electron configuration. The hydrogen atom now has a full 1s^2 electron configuration, while the chlorine atom has a full 1s^2 2s^2 2p^6 3s^2 3p^6 electron configuration.

The electron sharing between hydrogen and chlorine results in the formation of a covalent bond, specifically a polar covalent bond. In a polar covalent bond, the electrons are not shared equally between the atoms, leading to a partial positive charge on the hydrogen atom and a partial negative charge on the chlorine atom.

Electron Configuration and Chemical Bonding

The electron configuration of atoms plays a crucial role in determining the type of chemical bond formed between them. In the case of hydrogen chloride (HCl), the electron configuration of hydrogen and chlorine atoms allows for the formation of a covalent bond.

A covalent bond is formed when atoms share electrons to achieve a more stable electron configuration. In the case of HCl, the hydrogen atom shares its single electron with the chlorine atom, resulting in the formation of a covalent bond.

The covalent bond in HCl is classified as a polar covalent bond. In a polar covalent bond, the electrons are not shared equally between the atoms, leading to a partial positive charge on one atom and a partial negative charge on the other. In HCl, the chlorine atom attracts the shared electron pair more strongly than the hydrogen atom, resulting in a partial negative charge on the chlorine atom and a partial positive charge on the hydrogen atom.

Summary

In summary, the electron configuration of hydrogen is 1s^1, while the electron configuration of chlorine is 1s^2 2s^2 2p^6 3s^2 3p^5. The hydrogen chloride (HCl) molecule is formed through the sharing of electrons between hydrogen and chlorine atoms, resulting in the formation of a polar covalent bond.
