Question

Which element is least likely to be metallic

Answer 1

The element that is least likely to be metallic is a nonmetal.

Step-by-step explanation:

Metallic character refers to the level of reactivity of a metal. As you move across the periodic table from left to right, the metallic character decreases. So, the element that is least likely to be metallic would be found on the right side of the periodic table. Nonmetal elements are located on the right side of the periodic table, so the element that is least likely to be metallic is a nonmetal.

Answer 2

Helium because it's apart of the noble gases family
