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 set that contains a limited or countable number of elements. For example, the set of natural numbers from 1 to 10 is a finite set because it has exactly ten elements. In contrast, an infinite set has no bounds and contains an uncountable number of elements, such as the set of all natural numbers. Finite sets can be characterized by their cardinality, which is a measure of the number of elements in the set.
