Chemical symbol B represents the element Boron. Boron is a p block element.
If every element of A is an element of B then A is a subset of B.
Element : Boron
A is a subset of a set B if every element of A is also an element of B.
a element b\c it has no other elements in the equation
B stands for Boron on the periodic table.
Field Axioms are assumed truths regarding a collection of items in a field. Let a, b, c be elements of a field F. Then: Commutativity: a+b=b+a and a*b=b*a Associativity: (a+b)+c=a+(b+c) and (a*b)*c = a*(b*c) Distributivity: a*(b+c)=a*b+b*c Existence of Neutral Elements: There exists a zero element 0 and identify element i, such that, a+0=a a*i=a Existence of Inverses: There is an element -a such that, a+(-a)=0 for each a unequal to the zero element, there exists an a' such that a*a'=1
An element is a part of a compound.
Subset : The symbols ⊂ and ⊃(subset) A ⊆ B means every element of A is also an element of B
Boron
yes it is

Elements can be an element of a set. Lets say you have a set of numbers like A{2,3,5,8,45,86,9,1} B{2,7,0,100} all those numbers are called elements of that set 2 is an element of set A and B 100 is an element of set B 45 is an element of set A
