draw the lewis structure of sicl4. include all the lone pairs.
Answer
Explanation:
Step1: Determine valence - electrons
Silicon (Si) has 4 valence electrons and each chlorine (Cl) has 7 valence electrons. So for SiCl₄, the total number of valence electrons is (4 + 4\times7=32) electrons.
Step2: Place the central atom
Si is the central atom. Connect each Cl atom to the Si atom with a single bond. Each single bond uses 2 electrons, so 4 single bonds use (4\times2 = 8) electrons.
Step3: Distribute remaining electrons
We have (32-8 = 24) electrons left. Place these electrons as lone - pairs on the Cl atoms. Each Cl atom can accommodate 3 lone - pairs (6 electrons). So each of the 4 Cl atoms gets 3 lone - pairs.
Answer:
Si is in the center with single bonds to 4 Cl atoms. Each Cl atom has 3 lone - pairs of electrons around it.
