There are a few elements that contain a metalloid. Some of these are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium and Polonium.
Name of the set which contains all elements is UNIVERSAL SET. It is usually represented by (U)
A unit set contains all the elements under consideration.
A set that contains no elements is called an empty set, often denoted by the symbol ∅ or {}. If a set contains a natural number of elements, it is simply referred to as a finite set. Thus, the classification of the set depends on whether it has zero elements (empty set) or a positive count of natural numbers.
It is a set that contains no elements: an empty set.
A null set is a set that contains no elements.
Empty set or null set
Metalloid
It is a set which contains a finite number of elements.
The universal set.
It is a set that contains no elements - an empty set.
Gases and metals are not metalloids.
A finite set is a collection of distinct elements that contains a specific, countable number of items. This means that the number of elements in the set can be enumerated, and there is a last element in the set. For example, the set of integers from 1 to 10 is finite because it contains exactly ten elements. In contrast, an infinite set has an unbounded number of elements, such as the set of all integers.
