Answer 1

1. VSEPR stands for Valence Shell Electron Pair Repulsion.2. The main assumption of the VSEPR Theory is that electron pairs in the valence shell of an atom repel each other and try to stay as far apart as possible to minimize repulsion.3. The VSEPR Theory tells us that the behavior of valence-level electrons in a molecule is determined by the repulsion between electron pairs, which leads to the arrangement of atoms in a way that minimizes electron pair repulsion.4. A lone pair of electrons refers to a pair of valence electrons that are not shared with another atom and are not involved in bonding. A bonded pair of electrons refers to a pair of valence electrons that are shared between two atoms and are involved in bonding.5. The presence of a lone pair of electrons can affect the geometrical shape of a molecule by causing a distortion in the arrangement of atoms. This is because lone pairs occupy more space than bonded pairs, leading to a repulsion that pushes other electron pairs away and changes the shape of the molecule.
