Question

define the following with examples (a)chemical bond (b)Lewis symbol or dot structure (c)octet rule​

Answer 1

a. A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

b. Lewis symbols (also known as Lewis dot diagrams or electron dot diagrams) are diagrams that represent the valence electrons of an atom. Lewis structures (also known as Lewis dot structures or electron dot structures) are diagrams that represent the valence electrons of atoms within a molecule.

c. 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.

Answer 2

Explanation:

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 8 electrons in its valence shell , giving it the same electronic configuration as a noble gas
