Its actually electron pair repulsion. Its
the principle that electron pairs around a central atom tend to orient themselves as far apart as possible. Electron pair repulsion is used to predict the geometry of a molecule or a polyatomic ion.

Is it true that electrons are arranged in different energy levels in an atom?
It simply means that electrons can only have certain energies. These "levels" are often in terms of n, such as n1, n2, n3, and so on. Let's say that n1=1000 eV (a unit for energy) and n2=2000 eV. It would be impossible for an electron in an atom to have any energy between those two values. This follows true for any energy level; this can be shown better like this: there can be no electron energy found between nx and nx+1 when the electron is in an atom.
Define free radical?
a group of atoms ith an unpaire electron
How did Lewis define an acid?
An acid is a species which can accept an electron pair.
Define ionization energy of an element?
The energy required to remove an electron~ Apex! :D
Define negative charge without using mass of electron?
Mass and charge are not connected. Negative charge is the charge carried by an electron.
Define electron volt?
An electron volt is a unit of energy consisting of the energy resulting from the product of an electron through a potential of one volt, ev= .16E-18 Joules.
Define electrochemical corrosion?
Electorchemical corrosion is corrosion that is sped up due to electron movement, within the chemicals.
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
How do you define the term acid?
Acid, when referring to the science term are proton donors that yield hydronium ions in a water solution, or electron-pair acceptors that combine with electron-pair donors or bases.
Define main energy levels and quantum numbers?
The main energy levels are also known as the electron shells of an atom. An electron is permitted to be around an atom.
Do quantum numbers define the energy states and the orbitals available to an electron?
Yes, quantum numbers define the energy states and the orbitals available to an electron. The principal quantum number (n) determines the energy level or shell of an electron, the azimuthal quantum number (l) determines the shape or orbital type, the magnetic quantum number (m) determines the orientation of the orbital, and the spin quantum number (+1/2 or -1/2) determines the spin state of the electron. Together, these quantum numbers provide a complete description of the electron's state within an atom.
What does the term electron orbital describe?
An atom can be categorized as units and subunits, to begin with a shell, in it we have subshells followed by orbitals, each orbital has different shapes, an orbital can have a maximum of 2 electrons, we can define an orbital as a region where the possibility of finding an electron is maximum.
Is hydrogen carbonate the same as hydrogen as hydrogen ion?
A Hydrogen atom is one proton, one electron. The ion has lost the 1 electron, but it is still the same element, if that's what you mean. Protons are used to define what the element is.
