8. Define the Octet Rule. 9. A __ covalent bond results when electrons are shared equally. A __ covalent bond results when electrons are shared unequally.

The Octet Rule explains a chemical principle noting that elements by tendency combine such that each atom attains 8 electrons exactly in its outermost shell. These practice mirrors nature's pattern such as inert gases like Neon or Argon which hold completely filled valence shell.Answer to Question 9:【Explanation】: This question poses a statement about the covalent bond and requires an adequate clarification. The confusion here stems from the differentiation of electrons' allotment in a covalent bond.A Covalent Bond is invented as a result of elements or atoms, having comparable electronegativity potential, share electrons. Covalence varies in its distribution of the shared pair of the connecting electrons. If atoms involved are of the same elements, the electron sharing occurs evenly or equally speaking, we then discuss the concept of pure covalent bond or “non-polar covalent bond.”However, if the bond forms between atoms of two contrasting elements with atrial distinct electronegativity, the electrons' sharing trends slightly towards one atom, creating what is termed as a “polar covalent bond.”【Answer】: Statement 9 is true when a Covalent Bond is split sub-categorically, - Polar covalent and the Non-Polar covalent. Innate in the Polar covalent bond, electrons are not doled evenly across an atom due to disparities in electronegativity. At the paradox, Non-polar covalent bonds illustrate the sharing of electrons equally.
