Question

1. which statement best describes the name and location on the periodic table of the elements with the highest and lowest electronegativity, respectively? fluorine, on the upper right, has the highest electronegativity, and francium, on the lower left, has the lowest electronegativity helium, on the upper right, has the highest electronegativity, and francium, on the lower left, has the lowest electronegativity neon, on the upper right, has the highest electronegativity, and francium, on the lower left, has the lowest electronegativity hydrogen, on the upper left, has the highest electronegativity, and radon, on the lower right, has the lowest electronegativity. clear all

Explanation:

Electronegativity increases from left - to - right across a period and decreases from top - to - bottom within a group on the periodic table. Fluorine is in the upper right (Group 17, Period 2) and has the highest electronegativity. Francium is in the lower left (Group 1, Period 7) and has one of the lowest electronegativities. Noble gases like Helium, Neon have stable electron configurations and do not readily attract electrons, so their electronegativities are not the highest. Hydrogen is not the most electronegative element and Radon is not the least electronegative.

Answer:

Fluorine, on the upper right, has the highest electronegativity, and Francium, on the lower left, has the lowest electronegativity
