Question

Determine how the following bonds are made using Lewis dots structures

Answer 1

1.)
`Ca^(2+)+2Cl^-\rightarrow CaCl_2`

Calcium has 2 valence electrons and chlorine has 7 valence electrons. For neutral molecule, 2 chlorine atoms share their valence electrons with 1 calcium atom. The bonds are formed between the calcium and chlorine atom.

2.)
`Al^(3+)+3F^-\rightarrow AlF_3`

Aluminium has 3 valence electrons and fluorine has 7 valence electrons. For neutral molecule, 3 fluorine atoms share their valence electrons with 1 aluminium atom. The bonds are formed between the aluminium and fluorine atom.

3.)
`H^(+)+Cl^-\rightarrow HCl`

Hydrogen has 1 valence electron and chlorine has 7 valence electrons. For neutral molecule, 1 chlorine atom share their valence electrons with 1 hydrogen atom. The bonds are formed between the hydrogen and chlorine atom.

4.)
`2H^(+)+S^(2-)\rightarrow H_2S`

Hydrogen has 1 valence electron and sulfur has 6 valence electrons. For neutral molecule, 2 hydrogen atoms share their valence electrons with 1 sulfur atom. The bonds are formed between the hydrogen and sulfur atom.

5.)
`Cl^(-)+Cl^-\rightarrow Cl_2`

Chlorine has 7 valence electrons. For neutral molecule, 1 chlorine atom share their valence electrons with 1 chlorine atom. The bonds are formed between chlorine and chlorine atom.
