Why SbF5 is more stable than BiF5?
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.
What are the VSEPR numbers around either Nitrogen atom?
The VSEPR (Valence Shell Electron Pair Repulsion) number around a nitrogen atom is determined by the number of bonding pairs and lone pairs of electrons in its valence shell. For example, in ammonia (NH₃), nitrogen has three bonding pairs and one lone pair, giving it a VSEPR number of 4, leading to a trigonal pyramidal geometry. In nitrogen gas (N₂), there are two bonding pairs and no lone pairs, resulting in a VSEPR number of 2, which corresponds to a linear geometry.
What compound would have a vsepr formula in AX3?
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.
What are repelled in VSEPR theory?
Electron pairs
What is the difference between the Lewis model and the valence-shell electron pair repulsion (VSEPR) model?
VSEPR only shows the geometric shape of the element
What is the compound BiF5 called?
The compound BiF5 is called bismuth pentafluoride.

What is the VSEPR formula of PF3?
Ax3e
What are the number of single and double bonds in SO2 according to VSEPR theory?
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
