What is the primary reason for the high electronegativity of halogens? (2020)
Step 1: Understand what electronegativity means. It is the ability of an atom to attract electrons.
Step 2: Learn about halogens. They are a group of elements in the periodic table, including fluorine, chlorine, bromine, iodine, and astatine.
Step 3: Know that halogens are very close to having a full outer electron shell. They need only one more electron to be stable.
Step 4: Recognize that high ionization energy means it takes a lot of energy to remove an electron from an atom.
Step 5: Realize that halogens have high ionization energy, which means they hold onto their electrons tightly and can attract other electrons effectively.
Step 6: Conclude that because halogens can attract electrons well due to their high ionization energy, they have high electronegativity.
