Question

1. arrange the following elements in order from smallest electronegativity to largest electronegativity. periodic table smallest electronegativity → largest electronegativity a b c choices: al c na

Explanation:

Electronegativity increases across a period from left to right in the periodic table. Sodium (Na) is in group 1, aluminum (Al) is in group 13, and carbon (C) is in group 14. Since Na is further to the left than Al, and C is further to the right than Al, Na has the lowest electronegativity, followed by Al, and then C.

Answer:

A. Na, B. Al, C. C
