What is the electron-pair geometry around the Si atom in SiH4 is?

The electron-pair geometry around the silicon (Si) atom in SiH4 is tetrahedral. This is because silicon is surrounded by four hydrogen (H) atoms, each forming a single bond with silicon. The four electron pairs (bonding pairs) repel each other and adopt a spatial arrangement that minimizes this repulsion, resulting in a tetrahedral shape with bond angles of approximately 109.5 degrees.
