The bonding in carbon dioxide (CO 2): all atoms are surrounded by 8 electrons, fulfilling the octet rule.. 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.
Although such compounds are not intrinsically unstable, they instead tend to dimerize or even polymerize. [1] Moreover, the multiple bonds of the elements with n =2 are much stronger than usual, because lone pair repulsion weakens their sigma bonding but not their pi bonding.) [ 2 ] An example is the rapid polymerization that occurs upon ...
In chemistry, electron counting is a formalism for assigning a number of valence electrons to individual atoms in a molecule. It is used for classifying compounds and for explaining or predicting their electronic structure and bonding. [1]

A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

Nuclear charge is defined as the number of protons in the nucleus of an element.Thus, from left-to-right of a period and top-to-bottom of a group, as the number of protons in the nucleus increases, the nuclear charge will also increase. [8]
