Im not for sure, but I believe it would be the VSEPR theory.

since electrons are negatively charged, and the negative charges cause the electrons to repel each other making the atoms spread out as much as possible.

What is the VSEPR of AlCl3?

Valence shell electron pair repulsion (VSEPR) theory is a model in chemistry used to predict the shape of individual molecules based upon the extent of electron-pair electrostatic repulsion.[1] It is also named Gillespie-Nyholm theory after its two main developers. The acronym "VSEPR" is sometimes pronounced "vesper" for ease of pronunciation; however, the phonetic pronunciation is technically more correct. Aluminium chloride (AlCl3) is the main compound of aluminium and chlorine. It is white, but samples are often contaminated with iron trichloride, giving it a yellow colour. The solid has a low melting and boiling point. It is mainly produced and consumed in the production of aluminium metal, but large amounts are also used in other areas of chemical industry. The compound is often cited as a Lewis acid. It is an example of an inorganic compound that "cracks" at mild temperature, reversibly changing from a polymer to a molecule


What is the specific amount of energy an electron has?

An electron has no specific amount of energy. According to Bohr's Model of hydrogen atom, the energy of an electron in a shell is given by: E=-13.6x Z2/n2 E.V. Where Z is the atomic number of the atom, n is the shell number and E.V. is electron volt, the unit for energy 1E.V. = 1.6 x 10-19 J. But the Bohr's model was rejected and quantum mechanical model of an atom came into force where n=principal quantum number and l=Azimuthal quantum number are used to determine the energy of an atom. 'n' determines the energy to a larger extent and 'l' to a little extent.


What is the outermost electronic configuration of the most electronegative element?

Electronegativity is, to some extent, a subjective value (though based on a composite of actually measurable physical properties). The highest electronegativity is usually assigned to fluorine. The electron configuration of fluorine's outermost shell is 2s2 2p5.


Which bond is pure covalent bond?

Every bond formed show both ionic and covalent character to different extent. Even a bond formed between similar atoms show a slight ionic character as their electron distribution is most probably asymmetrical.


Which group or famil has the lowest ionization energy?

Group 1 because across group 1 to 8 nuclear force of attraction increases to a significant extent and as a result greater amount of energy is needed to remove an electron. More specifically Fr has the lowest IE and He has the highest

What is the relationship between the molecular bond strength of a solute and the extent to which the solute and the extent to which the solute ionizes in solution?

The extent to which a solute ionizes in solution is not related to the bond strength of the solute. The extent of the ionization will have to do with the identity of the solvent and the bonds that it can form with the solute.


Define Polarizability What is polarizability?

It is a measure of how easily an electron cloud is distorted by an electric field. Electron cloud will belong to atom, molecule or Ion. It is the quantitative measurement of the extent to which the electronic cloud can be polarized


What is the function of the lone pair electrons in the molecules?

In terms of struture, lone pairs contribute helping a molecule acquire a shape as dictated by VSEPR Theory (Valence Shell Electron Pair Repulsion Theory). Regarding chemical properties lone pair/s of electrons can make a molecule act as a Lewis base (like ammonia) in the reaction mixtures the extent of which depends on various other features in the structure of molecule.

Would you expect the second electron gain enthalpy of O as positive more negative or less negative than the first Justify your answer?

The second electron gain of an oxygen atom would be expected to be less negative. The reason for this outcome is that the oxygen atom gaining a second electron already has one electron and thus a negative charge. This negative charge repels the second electron to some extent, making the enthalpy of this process less negative than when the first electron was added to the neutral oxygen atom.

Do scientist believe in the big bang theory?

To the same extent that they believe gravity exists away from our planet, and for the same reason: scientists observe the predictions made by both ideas. Planets move around our Sun just as gravity predicts they will, and our Universe is exactly as predicted by Big Bang Cosmology.

OK, they all go to Africa, and get a message from this little girl that the sky's gonna fall. then angel predicts that fang's gonna die first. max & fang get closer and max goes 2 every possible extent 2 protect him. That is all anybody knows


How does the size of an atomic nucleus compare with the size of the whole atom?

Think of the sun as the nucleus and the oort cloud (past pluto) as where the electron orbitals start. The size (volume) of the nucleus is tiny compared to the size (volume) of the atom (defined by the extent of the electron cloud).
