Final Answer:
1) Li + Cl → LiCl
Atoms: Li, Cl
Valence electrons: Li = 1, Cl = 7
Electron transfer from/to each atom: Li loses 1 e⁻, Cl gains 1 e⁻
Ions formed in the product: Li⁺, Cl⁻
2) Ca + O → CaO
Atoms: Ca, O
Valence electrons: Ca = 2, O = 6
Electron transfer from/to each atom: Ca loses 2 e⁻, O gains 2 e⁻
Ions formed in the product: Ca²⁺, O²⁻
3) Be + F → BeF₂
Atoms: Be, F
Valence electrons: Be = 2, F = 7
Electron transfer from/to each atom: Be loses 2 e⁻ (1 to each F), each F gains 1 e⁻
Ions formed in the product: Be²⁺, F⁻ (two of them)
4) Mg + S → MgS
Atoms: Mg, S
Valence electrons: Mg = 2, S = 6
Electron transfer from/to each atom: Mg loses 2 e⁻, S gains 2 e⁻
Ions formed in the product: Mg²⁺, S²⁻
5) K + F → KF
Atoms: K, F
Valence electrons: K = 1, F = 7
Electron transfer from/to each atom: K loses 1 e⁻, F gains 1 e⁻
Ions formed in the product: K⁺, F⁻
