Which of the following statements is not correct? Group 7 elements
Answer Details
The statement that is not correct about Group 7 elements is: "have relatively low ionization potentials."
Explanation:
Group 7 elements, also known as halogens, include fluorine, chlorine, bromine, iodine, and astatine. These elements are diatomic, meaning that they exist naturally as a molecule containing two atoms of the same element. They are highly electronegative, which means that they have a strong attraction for electrons. This high electronegativity makes them good oxidizing agents since they readily accept electrons from other atoms.
However, the statement that Group 7 elements have relatively low ionization potentials is incorrect. Ionization potential refers to the amount of energy required to remove an electron from an atom or ion. Halogens have relatively high ionization potentials since they have a strong attraction for their outermost electrons. This means that it takes a significant amount of energy to remove an electron from a halogen atom or ion, making it less likely to form a cation.
Therefore, the correct answer is "have relatively low ionization potentials."
