nd ciccuIcty Because a. bonding electrons are free to roam among any of the atoms in the metal piece b. electrons are transferred in covalent bonds c. electrons are shared in ionic bond d. electrons are locked into a fixed location Difference in Electronegativity and Percent Ionic Character (p.13-15). Match the difference in electronegativity and percent ionic character with the following molecules. (Hint: Find the electronegativity for each element on the Periodic Table. The atom with the highes electronegativity pulls the electrons towards itself. Subtract to find the difference. Match the difference in electonegativity with the values across the top of the periodic table. Percent ionic character is listed below the electronegativity difference.)

Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
