Valence Electrons: Shape of Molecule

[mrsbinns]

why don't valence and core electrons affect the shape of the molecule?
why don't double and triple bonds affect the shape of the molecule?

 

[Stevedye56]

Double and tripple bonds do affect the shape. Single bonds are 109* double are 120* and tripple bonds are 180*. Bonds clearly effect the molecules shape.

Valence electrons play a crucial role in determining the chemical and physical properties of atoms and molecules. They are the outermost electrons of an atom and are involved in chemical bonding and reactions. The shape of a molecule is determined by the arrangement of its atoms and the bonding between them.

Valence electrons are responsible for forming covalent bonds between atoms, which can result in different shapes of molecules such as linear, bent, trigonal planar, etc. However, core electrons, which are the inner electrons of an atom, do not participate in bonding and therefore do not affect the shape of a molecule.

Double and triple bonds do not affect the shape of a molecule because they are formed by the sharing of electrons between atoms, just like single bonds. The only difference is that double and triple bonds involve the sharing of two or three pairs of electrons, respectively. These bonds do not change the overall arrangement of atoms in a molecule, and therefore do not affect its shape.

In summary, valence electrons are responsible for the shape of a molecule as they are involved in bonding and determine the arrangement of atoms. Core electrons and double/triple bonds do not affect the shape of a molecule as they do not participate in bonding or change the overall arrangement of atoms.
