State VSEPR Theory.
The electron pairs in the valence shell surrounding a terminal atom repel one another and arrange themselves as far apart as possible to minimize the repulsion.
The electron pairs in the valence shell surrounding a central atom repel one another and arrange themselves as far apart as possible to minimize the repulsion.
The electron pairs in the valence shell surrounding a central atom repel one another and arrange themselves as close as possible to minimize the repulsion.
