Final answer:
The Lewis structure of a compound formed from aluminum (Al) and phosphorus (P), such as AlP, involves the sharing of valence electrons to achieve stable electron configurations, where Al shares its three valence electrons with three of the five from P to form a covalent bond satisfying the octet rule.
Step-by-step explanation:
Drawing the Lewis Structure for Al and P
When drawing the Lewis structure for a compound formed from aluminum (Al) and phosphorus (P), it is essential to consider the valence electrons of each element. Aluminum has three valence electrons, while phosphorus has five. When these two elements form a compound, they tend to combine in such a way that they reach a stable electron configuration, often attempting to satisfy the octet rule, where elements strive to have eight valence electrons.
This leads to the formation of AlP, aluminum phosphide, in which each aluminum atom shares its three valence electrons with three of the five valence electrons from phosphorus, resulting in a covalent bond. The Lewis structure for AlP would have one Al atom with three dots around it representing its valence electrons paired with three of the five dots around the P atom, reflecting a transfer of electrons to form a stable bond.
This method not only applies to simple molecules but also more complex structures. For instance, the diatomic molecule P2 comprises two phosphorus atoms bonded together, each sharing three electrons to complete their valence shells, leading to a stable P2 molecule with a triple bond.
