• Dot Structure (ions): Lithium ion (Li⁺) has no outer shell electrons; Phosphide ion (P³⁻) has eight outer shell electrons.
• Formula Unit: Li₃P
• Name: Lithium Phosphide

Calcium Bromide

• Atoms: Calcium (Ca), Bromine (Br)
• Lewis Structures (atoms): Calcium (Ca) has two valence electrons; Bromine (Br) has seven valence electrons. (Visual representations of these structures would be helpful here, but text-based is sufficient.)
• Ions: Calcium loses two electrons to form Ca²⁺; bromine gains one electron to form Br⁻.
• Dot Structure (ions): Calcium ion (Ca²⁺) has no outer shell electrons; Bromide ion (Br⁻) has eight outer shell electrons.
• Formula Unit: CaBr₂
• Name: Calcium Bromide

Gallium Sulfide

• Atoms: Gallium (Ga), Sulfur (S)
• Lewis Structures (atoms): Gallium (Ga) has three valence electrons; Sulfur (S) has six valence electrons. (Visual representations of these structures would be helpful here, but text-based is sufficient.)
• Ions: Gallium loses three electrons to form Ga³⁺; sulfur gains two electrons to form S²⁻.
