Answer 2

Molecular Formation Schemes

Na2: The formation of a sodium molecule (Na2) involves the sharing of two electrons between the two sodium atoms, resulting in the formation of a stable covalent bond. This can be represented as: ``` Na + Na → Na2 ``` The Lewis structure of Na2 would show the two sodium atoms sharing a pair of electrons between them.

Br2: The formation of a bromine molecule (Br2) also involves the sharing of two electrons between the two bromine atoms, forming a stable covalent bond. The formation can be represented as: ``` Br + Br → Br2 ``` The Lewis structure of Br2 would depict the two bromine atoms sharing a pair of electrons.

O2: The formation of an oxygen molecule (O2) occurs through the sharing of two pairs of electrons between the two oxygen atoms, resulting in a double covalent bond. The formation can be represented as: ``` O + O → O2 ``` The Lewis structure of O2 would illustrate the two oxygen atoms sharing two pairs of electrons.

N2: The formation of a nitrogen molecule (N2) also involves the sharing of three pairs of electrons between the two nitrogen atoms, leading to the formation of a triple covalent bond. This can be represented as: ``` N + N → N2 ``` The Lewis structure of N2 would show the two nitrogen atoms sharing three pairs of electrons.

These molecular formation schemes are based on the principles of covalent bonding, where atoms share electrons to achieve a stable electron configuration.
