Question

lewis dot structure for BeF2 and SiCl4

Answer 1

A step-by-step explanation of how to draw the SiCl4 Lewis Structure (Silicon Tetrachloride ). For the SiCl4 Lewis structure we first count the valence electrons for the SiCl4 molecule using the periodic table. ... Silicon (Si) is the least electronegative atom and goes at the center of the structure.

Answer 2

Bef2

Q = total no. Of electrons of each atom

= 2+7+7

= 16

Bond pair electrons = 2 x no. Of bonds

= 4

Lone pair electrons = q - BPE

= 16 - 4

= 12

Sicl4

Q = 4+7+7+7+7

= 32

BPE = 8

LPE = 32 - 8 = 24
