Fundamentals

The 100+ existing elements  are organized into a table known as the Periodic Table. These elements can be categorized as being either metals, nonmetals, or metalloids. The location of the element on the Periodic Table yields some clues about whether an element is a metal, a nonmetal, or a metalloid.

There are two similar versions of  questions in this Question Group.  One of the two versions is shown below.
 

Version 1:

Consider the list of eight elements. Identify all the elements that are metals.
Bromine (Br)
Carbon (C)
Mercury (Hg)
Neon (Ne)
Potassium (K)
Thallium (Tl)
Uranium (U)
Zirconium (Zr)
 

How to Think About This Situation

To be successful at this question you will need to apply an understanding of how the location of an element within the Periodic Table can serve as an indicator as to whether it is a metal, nonmetal, or metalloid. The infographic below includes information on this topic. Study the infographic and apply what you learn.
