An element is an item that belongs to a set.
Not sure about maening, but a unit set is a set containing only one element.
If the symbol is like "< " but rounded , then set A < B means every element of set A is found in set B, but there is some element of set B that is not in A. In words it says that A is a proper subset of B.
I believe you are talking about subsets. The empty set (set with no elements) is a subset of any set, including of the empty set. ("If an object is an element of set A, then it is also an element of set B." Since no element is an element of set A, the statement is vacuously true.)
No. An empty set is a subset of every set but it is not an element of every set.

A relation is any set of ordered pairs.A function is a relation in which each first element corresponds to exactly one second element
an empty set does not have any element

Each object in a set is an individual element that is distinct from the others within the set. Sets are collections of unique objects, meaning that each object can only appear once in a set.
No. An empty set is a subset of every set but it is not an element of every set.
element of a set is when two numbers are formed together to form a set and the element is based on a binary question or answer.
The empty element is a subset of any set--the empty set is even a subset of itself. But it is not an element of every set; in particular, the empty set cannot be an element of itself because the empty set has no elements.
No, but it is a subset of every set.It is an element of the power set of every set.
Use commas to set off nonrestrictive elements. Do not use commas to set off restrictive elements. A restrictive element defines or limits the meaning of the word it modifies and is therefore essential to the meaning of the sentence.
