Question

Determine how the following bonds are made using Lewis dots structures

Answer 1

Answer :

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.
