Question

Which of the following elements is most nonmetallic - most wanting of electrons?

A. Oxygen
B. Fluorine
C. Sulfur
D. Bromine

Answer 1

B. Fluorine

Explanation:

Nonmetallic character increases from bottom to top in a Group and from left to right in a period (see image).

Thus, the most nonmetallic elements are at the upper right corner of the Periodic Table.

We ignore the noble gases, because they are quite unreactive.

So, the element that most “wants” an electron is fluorine.
