Elements that have properties between metals, nonmetals, and metalloids are called elements
The answer is: metalloids
The term “metallic elements” refers to a large number of elements that have their own characteristics, and these elements belong to two main categories, metalloids and non-metals. But there is a class of elements that have properties centered between metals and non-metals, and these elements are called metalloids. These elements are characterized by the fact that they are similar in some properties to metals, such as their ability to conduct heat and electricity, but they differ from them in some other properties. The range of use of these elements extends in a large number of fields, including industrial and technological, which makes them elements of great importance and value in the modern world.
