Question

A chemist wants to use an element with a large electronegativity for an experiment. Based on trends in the periodic table, which of the following groups has the largest electronegativity. Alkali Metals Halogens Noble Gases Alkaline Earth Metals

Answer 1

Answer:

Halogens

Explanation:

Electronegativity increases from left to right in the Periodic Table (see image).

We ignore the elements of Group 18 (the noble gases) because they are quite unreactive.

So, the most electronegative elements are those in Group 17 (the halogens).
