The Octet Rule: Help, Definition, and Exceptions
Definition from Corrosionpedia [1]
The octet rule states that atoms gain or lose electrons to attain an outer shell electron configuration nearest that of a noble gas. The attractive force between atoms is informally measured with this rule.
It also determines whether electrons are added or lost through chemical reactions, and measures chemical reactivity of atoms based upon their specific electron configuration.. The octet rule refers to the phenomenon whereby elements will usually form bonds so as to attain eight electrons in their valence shell in order to become noble gases
The bonding patterns and reactivity of such elements can easily be predicted by applying this rule.. Due to the stability of their configuration that is its being full octet with no charge, such gases have no reason to react
The Octet Rule [2]
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds
Only the s and p electrons are involved in the octet rule, making it useful for the main group elements (elements not in the transition metal or inner-transition metal blocks); an octet in these atoms corresponds to an electron configurations ending with \(s^2p^6\).. In 1904, Richard Abegg formulated what is now known as Abegg’s rule, which states that the difference between the maximum positive and negative valences of an element is frequently eight
Atoms will react to get in the most stable state possible. A complete octet is very stable because all orbitals will be full
An octet rule occurs when atoms gain , lose, or share electrons to achieve a full valence shell of 8 electrons.. See related answer herre: brainly.com/question/19384027
A scientist examining the periodic table sees that the element magnesium (Mg) has the atomic number of 12. Based on this knowledge, what does the scientist immediately know is true about magnesium atoms?
This is because the atomic number of an element indicates how many protons there are. A scientist discovers that an atom with a mass number of 14 contains eight electrons
Detailed Explanation with Examples, Exceptions [4]
The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons. It is based on the observation that the atoms of the main group elements have a tendency to participate in chemical bonding in such a way that each atom of the resulting molecule has eight electrons in the valence shell
The molecules of the halogens, oxygen, nitrogen, and carbon are known to obey the octet rule. In general, the elements that obey this rule include the s-block elements and the p-block elements (except hydrogen, helium, and lithium).
The shared electrons fulfil the valency requirements of both the bonded atoms. Thus, it can be noted that both the oxygen atoms and the carbon atom have an octet configuration in the CO2 molecule.
Octet rule [5]
The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens; although more generally the rule is applicable for the s-block and p-block of the periodic table
The valence electrons can be counted using a Lewis electron dot diagram as shown at the right for carbon dioxide. The electrons shared by the two atoms in a covalent bond are counted twice, once for each atom
All four of these electrons are counted in both the carbon octet and the oxygen octet, so that both atoms are considered to obey the octet rule.. Ionic bonding is common between pairs of atoms, where one of the pair is a metal of low electronegativity (such as sodium) and the second a nonmetal of high electronegativity (such as chlorine).

Octet Rule [8]
In this tutorial, you will learn what the octet rule is, the exceptions to the rule, and see examples and problems.. The octet rule is that an atom will be most stable when surrounded by 8 electrons in the valence shell
A configuration that has eight electrons is also referred to as the ‘noble-gas configuration’.. The noble gasses are the only atoms with eight valence electrons and therefore tend not to react or bond with other atoms and molecules
Hence why other atoms with a full octet are referred to as in ‘noble-gas configuration’.. The filled valence octet means that the s and p-orbitals are filled
Octet Rule – Easy Hard Science [9]
It allows us to determine the atomic structure of most chemicals. The octet rule is also used in determining the names and formulas for many chemicals.
It is a direct consequence that the periodic table has 8 main columns (the ones near the top).. The periodic table is shown below with the main 8 columns of the periodic table
The number 1-8 indicates the number of valence electrons for some atom. Atoms are unstable unless they have 8 valence electrons
Explain the Octet Rule & Give Examples [10]
In chemistry, the octet rule explains how atoms of different elements combine to form molecules. Many elements are not chemically stable by themselves; by sharing electrons, an atom gains stability
The electrons that surround the core of every atom are organized into complex, concentric regions called shells. Chemists are most interested in the outermost, or valence, shells of atoms because they hold the electrons that take part in chemical reactions
On the other hand, atoms with partial valence shells quickly combine with their neighbors to make molecules.. For most elements, the valence shell takes eight electrons to fill

Choose the statement that best describes the PbCl4 molecule. – Choose the statement that best describes the PbCl4 molecule in the gas phase
This implies, the central atom Pb has 4 bonds surrounding it with no lone pairs. Hence PbCl₄ possesses a tetrahedral geometry with bond angles of 109.5°.
PbCl₄ possesses a tetrahedral geometry, where the dipole moment of each Pb-Cl bond cancels out each other making the net dipole moment of the molecule 0. C)In PbCl₄ molecule, the individual dipole moments cancel out each other, making the molecule non-polar
