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