Discuss the shape of the following molecules using the $VSEPR$ model: $BeCl_2, BCl_3, SiCl_4, AsF_5, H_2S, PH_3$.

(N/A) $BeCl_2$: The central atom has no lone pair and two bond pairs ($AB_2$ type). Hence,it has a linear shape.
$BCl_3$: The central atom has no lone pair and three bond pairs ($AB_3$ type). Hence,it is trigonal planar.
$SiCl_4$: The central atom has no lone pair and four bond pairs ($AB_4$ type). Hence,it is tetrahedral.
$AsF_5$: The central atom has no lone pair and five bond pairs ($AB_5$ type). Hence,it is trigonal bipyramidal.
$H_2S$: The central atom has two lone pairs and two bond pairs ($AB_2E_2$ type). Hence,it is bent or $V$-shaped.
$PH_3$: The central atom has one lone pair and three bond pairs ($AB_3E$ type). Hence,it is trigonal pyramidal.
