SbF5 (antimony pentafluoride) is more stable than BiF5 (bismuth pentafluoride) primarily due to the differences in the central atoms' electronegativity and size. Antimony, being in the fifth group of the periodic table, has a suitable size and effective nuclear charge that allows for better bonding with fluorine atoms. In contrast, bismuth is larger and has a lower electronegativity, which leads to weaker Bi-F bonds and increased instability in BiF5. Additionally, the presence of lone pairs on bismuth contributes to steric and electronic repulsions, further destabilizing BiF5.
The Valence shell electron pair repulsion, or VSEPR is a simple technique for predicting the shape or geometry of atomic centers. The VSEPR formula is used in small molecules and molecular ions.

VSEPR only shows the geometric shape of the element
I believe it would be a T-shaped molecule because it has 3 bonding pairs and 2 lone pairs.
The compound BiF5 is called bismuth pentafluoride.
The VSEPR model is used mainly to determine molecular shape.
VSEPR notation is AX3E Tetra Pyramidal angle is 109.5 degrees sp3 hybridization VSEPR notation is AX3E Tetra Pyramidal angle is 109.5 degrees sp3 hybridization
VSEPR is a conceptual model, as it has not been directly observed.
The molecular geometry of CHCl3, according to VSEPR theory, is tetrahedral.
The molecular geometry of SO2 according to the VSEPR theory is bent.
Ax3e
According the VSEPR theory of molecular geometry, the geometry of SCl2 would be the same as H2O which is a bent angle
VSEPR relates to electron pair repulsion -and uses this effect to predict molecular geometry. You need to determine the bonding using lewis dot diagrams or some other methodology first before using VSEPR
