What is the difference between the arrangement of electron pairs and the shape of the molecules?
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.
What is the spatial arrangement of lone pairs and bonded pairs around the central atom?

What is shape in pbr3?
What is 'pbr3' ??? If you mean the chemical phosphorus bromide , the formula is 'PBr3'. NOTE the use of Capital letters. Ther shape is pyrsmidal, similarl to its group analogy ammonia.

How does number of electron pairs around central atom determine its shape?
The number of electron pairs around the central atom determines its shape by following the VSEPR theory, which states that electron pairs arrange themselves around the central atom to be as far apart from each other as possible. The arrangement of electron pairs gives rise to specific molecular geometries, which in turn determine the overall shape of the molecule.
What is the electron shell arrangement of caesium?
The electron shell arrangement of Ceasium is 2.8.8.18.18.1
How do you determine the shape of molecules?
The shape of molecules is determined by the number of bonding and non-bonding electron pairs around the central atom. The VSEPR (Valence Shell Electron Pair Repulsion) theory is commonly used to predict molecular geometry based on electron pairs' repulsion. The arrangement of these electron pairs results in different molecular shapes such as linear, trigonal planar, tetrahedral, and more.
What is VSEPR theory used for?
Valence shell electron pair repulsion theory, otherwise known as VSEPR theory, is used to predict the geometry of molecules. This is based on the number of electron pairs surrounding their central atoms. This is based on the idea that valence electron pairs surrounding and Adam generally repel each other, so their arrangement is based on the minimizing of said repulsion.
What is the electron arrangement for calcium?
Since the electron arrangement is 2,8,18, and 32, the electron arrangement for a calcium atom is 2,8, and 10.
