Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom

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.
The geometry of the molecule actually determines number of electron pairs on the central atom. The electron pairs will be arranged in such a way to minimize the repulsion and therefore, have the lowest possible energy.
Anything with six electron groups, keep in mind an electron group is a bonded atom or an electron pair, is an octahedral. Anything in an octahedral and a lone pair is the square pyramidal geometry. So all angles between the atoms are a little less than 90 degrees and the angle of the electron pair is greater than 90.
The arrangement of the electrons in an atom is known as its electron configuration.
An electron around an atom forms a sort of cloud; the cloud represents the probability distribution of finding the electron in different places. In the simplest case, this distribution is spherically symmetrical, but for the outer electrons, the distribution is more complicated. For more information, check the Wikipedia article on "Atomic orbital".
Electronegativity of each atom is what determines the electron distribution of a bond. The electronegativity of an atom affects its distance in its valence electrons and its atomic number.
An electron is a part of a atom, and an atom is part of a molecule, molecules make up a cell. So a cell is biggest.
An ionic molecule is formed.
Every elements have the electrons of an atom distribution or a molecule in molecular orbitals and it is called electron configuration. The element that can be grouped in the family with above electron configuration is called antimony.
Electron configuration for an atom is the distribution of electrons on atomic orbitals.
yes
Smallest to Largest.. - Electron - Proton - Atom - Compound - Molecule
Cell.
the distance from the nucleus at which the electron is most likely to be found
Ions are made for clothes can not be wrinkly An ion is formed when an atom [or molecule] gains or loses one or more electrons. If an atom or molecule gains an electron it acquires negative charge. If the atom or molecule loses an electron it becomes positively charged.
