Chapter 4, Problem 45P

Interpretation Introduction

Interpretation:

The electronegativity difference between A and B elements so the covalent bond will be polarshould be determined.

Concept Introduction:

• Valence electron: The electrons which are present in the outer most energy level are known as valence electron. This can be calculated by the group number of the element. Generally, the group number is same as the valence electrons of any elements.
• Octet rule: Generally, all atoms will lose, gain or share electrons to attain 8 valence electrons; the electron configuration of the nearest noble element.
• The covalent bond is a type of bond which formed by sharing of electrons between atoms. It forms between two non-metals.
