The element that Barbara found that is a gas and does not conduct heat or electricity is a nonmetal.
The element that Barbara found, which is a gas and does not conduct heat or electricity, falls under the category of nonmetal.
Nonmetals are elements that lack the typical characteristics of metals. They are generally poor conductors of heat and electricity. Nonmetals can exist in various states at room temperature, such as solids (like sulfur), liquids (like bromine), or gases (like oxygen).
To identify whether an element is a nonmetal, you can refer to the periodic table. Nonmetals are located on the upper-right side of the periodic table, excluding the elements touching the stair-step line (these are referred to as metalloids). Elements such as hydrogen, nitrogen, oxygen, fluorine, and chlorine are examples of nonmetals.
