It is the outer shell or valence shell electrons which are responsible for forming bonds and it is the arrangement of these electrons which determine molecular shape. The electrons are all negatively charged and so will repel each other.

WebbThe shape of a covalent molecule can be predicted using the Valence Shell Electron Pair Repulsion (VSEPR) theory. Very simply, VSEPR theory says that the valence electron pairs in a molecule will arrange themselves around the central atom(s) of the molecule so that the repulsion between their negative charges is as small as possible. WebbThe shape of a molecule is determined by the number of electron pairs in its outside shell and whether these electron pairs are bonding or non-bonding. The Valence Shell … Webb4 sep. 2024 · DNA molecules forms a 3D helix shape, bonded by hydrogen, whereas RNA remains as single strands of polynucleotide.

WebbTetrahedral. Molecules with four bonded electron pairs and no lone pairs form a tetrahedral shape. This is a regular triangular-based pyramid. All the bond angles are 109.5°. For example, the carbon in methane C H 4 has four valence electrons, and each electron is part of a pair bonded covalently to a hydrogen atom.

WebbThe Shapes of Molecules Different molecules have different shapes. The shape of a molecule is dictated by the arrangement of Electron Pairs. This is because Electron Pairs repel each other. The molecule settles in a state where the Electron Pairs are furthest apart from each other.
