These complicated properties are associated with theLewis theory of covalent bonding.According to this theory, the atoms tend to share their valence electrons. This allows each atom to create its own octet and the result is enhanced stability. (Ref.3) ...
In metallic bonding, the reason it is so good at conducting heat and electricity, is the electrons are loosely held in the atom. Also, the structural pattern of metals is hexagonal-close-packing (Francis, E . . .). Metallic bonds are when the electrons are shared and are able to move ...

This seemed satisfactory for compounds such as NaCl that were known to dissociate into ions when dissolved in water, but it failed to explain the bonding in non-electrolytes such as CH4. Atomic orbitals had not yet been thought of, but the concept of “valence” electrons was known, and ...
bonding pair) Some examples Practice drawing and naming Lewis Structures H 2 O CH 2 O Tricky ones! Try ozone O 3 What about ions? Count up all valence electrons that you are allowed to place. Still pick the central atom. Still have the correct number of ...
In this article, we will cover the topic of Covalent Bonding. These are the learning outcomes: Describe the formation of a covalent bond by the sharing of electrons. Draw the dot-and-cross diagram of simple covalent substances. Draw the structural formula of simple covalent substances. This ...

Covalent bonding occurs when an atom that needs an electron (an atom on the hunt) runs into another atom that also needs an electron. They each decide to share one or more electrons to form an electron pair. By each of them sharing an electron to form an electron pair, they form a bo...
The state balance of attractive forces and Repulsive forces between atoms when they share electron pairs is known as Covalent bonding An atom share electron with another atom of same or different element in order to attain stable electronic configuration of nearest inert gas i.e. Helium ,neon ,...
2. COVALENT BONDING, OCTET RULE, POLARITY, AND BASIC TYPES OF FORMULAS VALENCE ELECTRONS They are those found in the highest energy level of the atom, or outer shell. In the periodic table, the number of valence electrons is given by the group number. For example, in the second row, ...
