which statement best explains why the elements in group 18 do not have electronegativity values? (1 point)\nthe elements are too large.\nthe elements do not have electrons.\nthe elements have only one electron shell.\nthe elements have filled valence levels.
Answer
Brief Explanations:
Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond. Group 18 elements (noble gases) have filled valence shells (stable electron configurations). They do not tend to gain or share electrons as they are already stable, so they do not have electronegativity values.
- The first option is incorrect because size alone does not determine lack of electronegativity.
- The second option is wrong as all elements have electrons.
- The third option is incorrect as not all Group 18 elements have only one electron shell (e.g., argon has three).
Answer:
The elements have filled valence levels.
