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.

What circumstances is the molecular geometry around a central atom the same as the electron group geometry around the central atom?
The molecular geometry around a central atom is the same as the electron group geometry when there are no lone pairs of electrons on the central atom. In such cases, all electron groups (bonding pairs) are arranged symmetrically around the atom, leading to identical geometries. This typically occurs in molecules with linear, trigonal planar, or tetrahedral arrangements, depending on the number of bonding pairs.
What is the geometry of the central atom in selenium sulfide?
The central atom in selenium sulfide has a bent molecular geometry due to the presence of two lone pairs on the selenium atom. This results in a distorted tetrahedral arrangement around the selenium atom.
What is the electron-pair geometry around the Al atom in AlCl3?
tetrahedral
The electron pair geometry of each carbon atom in an alkane is what?
The electron pair geometry of each carbon atom in an alkane is tetrahedral. This is because each carbon atom is bonded to four other atoms, which results in a geometry where the electron pairs are distributed in a tetrahedral arrangement around the carbon atom.

tigonal pyramidal
What is the shape of silane?
Silane (SiH4) is a pyramid-shaped molecule with a central silicon atom bonded to four hydrogen atoms. The geometry of silane is tetrahedral, where the hydrogen atoms are positioned at the four corners of the tetrahedron around the central silicon atom.
What is the electron pair geometry of SiH4?
The molecule SiH4 has the silicon atom in the center (naturally) and the four hydrogen atoms are arranged very symmetrically at the corners of a tetrahedron, surrounding the silicon atom. Each hydrogen atom shares its single electron with the silicon, and the silicon shares its four valence electrons evenly with the four hydrogen atoms.
What is the geometry around central atom of ch4?
The geometry of Methane (CH4) is tetrahedron or tetrahedral
What is the hybridization of SiH4?
The hybridization of SiH4 is sp3, as the silicon atom utilizes its 1 s and 3 p orbitals to form four equivalent sp3 hybrid orbitals, each with a single hydrogen atom attached.
