True. The outer orbitals of a halogen are further from the nucleus and are thereby more polarizable.
What is a Halogen?
A halogen is a type of element found on the periodic table that belongs to the halogen group (Group 17). Halogens are nonmetallic elements that have seven valence electrons and react with other elements to form compounds. They are highly reactive and can combine with other elements to form compounds, such as salts, acids, and oxides. Halogens are important in industry and are used to make a wide variety of products, including plastics, pharmaceuticals, and insecticides.
A halogen's outer orbitals are further away from the nucleus, making them more polarizable due to their greater distance from the positively charged nucleus. Because of the greater distance, the orbitals are more susceptible to being pulled by the opposite charges of other molecules, allowing for greater polarizability.
