Answer 2

H2, Cl2, and Br2 are all diatomic molecules made up of two atoms.

H2 is a covalent compound, meaning that the two hydrogen atoms are bonded together by sharing electrons. In this case, each hydrogen atom contributes one electron, resulting in a single covalent bond between the two atoms. This type of bond is called a nonpolar covalent bond because the electrons are shared equally between the two atoms.

Cl2 is also a covalent compound, where the two chlorine atoms are bonded together by sharing electrons. In this case, each chlorine atom contributes one electron, resulting in a single covalent bond between the two atoms. Similar to H2, the bond in Cl2 is also a nonpolar covalent bond because the electrons are shared equally between the two atoms.

Br2, on the other hand, is also a covalent compound but with a slightly different type of bond. Each bromine atom contributes one electron, resulting in a single covalent bond between the two atoms. However, unlike H2 and Cl2, the bond in Br2 is a polar covalent bond because the electrons are not shared equally between the two atoms. This is due to the higher electronegativity of chlorine compared to hydrogen and bromine. The electronegativity difference between the two bromine atoms causes a slight imbalance in the electron distribution, resulting in a polar covalent bond.

In summary, H2 and Cl2 have nonpolar covalent bonds, while Br2 has a polar covalent bond.
