The shape of a molecule only describes the arrangement of bonds around a central atom. The arrangement of electron pairs describes how both the bonding and nonbonding electron pair are arranged. For example, in its molecular shape, a water molecule is describes as bent, with two hydrogen atoms bonded to an oxygen atom. However, the arrangement of electron pairs around the oxygen atom is tetrahedral as there are two bonding pairs (shared with the hydrogen) and also two nonbonding pairs.
they are the same. Lone pair is unshared pair of electrons and bond pair is shared pair of electron.
The electron pair geometry for CS2 is Linear.
the electron pair geometry would be trigonal planar because there is a lone pair on the oxygen atom. The molecular pair geometry would be bent
The electron geometry for silicon tetrafluoride (SiF4) is tetrahedral. This is because the central silicon atom is surrounded by four bonding pairs of electrons from the four fluorine atoms, with no lone pairs on the silicon. The tetrahedral arrangement minimizes electron pair repulsion, resulting in bond angles of approximately 109.5 degrees.
