Group A elements, known as metals, typically exhibit properties such as high conductivity, malleability, and ductility. They tend to lose electrons during chemical reactions, forming positive ions. In contrast, Group B elements, often referred to as transition metals, possess unique properties such as variable oxidation states and the ability to form colored compounds. They are also characterized by their complex electron configurations and are widely used as catalysts in various chemical reactions.

The members of the same group have similar physical and chemical properties.

The metalloid in group 13 is boron (B). It is characterized by properties that are intermediate between metals and nonmetals, making it unique among the elements in its group. Boron is commonly used in glass and ceramics, as well as in the production of certain alloys.
In the older periodic table, each group was divided into A & B sub-groups. The only problem with that was that there were two different conventions about which elements were labelled "A" and which were labelled "B". Groups 1 & 2 were clearly 'A' (elements like sodium and calcium) and 11 & 12 were clearly 'B' (elements like copper and zinc). But groups 3 through 10 were labelled 'A' in one convention and 'B' in another, and the opposite labels were used for groups 13 through 18.With the second labelling convention, groups labelled 'A' were known as 'main group elements', and groups labelled 'B' were 'transition metals', and that is still the case.Thus in the newer IUPAC scheme, groups 1, 2, and 13 through 18 are called 'main group elements'.
union means to group the given sets. where as intersection means to pick out the common elements from the given sets. if set a has 1,2,3 elements and B has 1,2,3,4,5. then its union will have 1,2,3,4,5 as its elements. and its intersection will have 1,2,3 as its elements.
A set is a collection of well defined objects known as elements Opperatons of sets are 1)union - the union of sets A and B is the set that contains all elements in A and all elements in B. intersection - given two sets A and B, the intersection of A and B is a set that contains all elements in common between A and B. compliments - given set A, A compliment is the set of all elements in the universal set but not in A difference - A-B is a set containing all elements in A that are not in B. symmetric difference - it is the sum of A and B minus A intersection B.

RH- and RH+ are not blood types, they are factors.
group 3 is B, Al, Ga, In and Tl
The difference of two sets A and B , to be denoted by A-B, is the set of all those elements which belong to A but not to B
Oh, dude, Group B elements are just a bunch of elements in the periodic table that have their outermost electron in a p orbital. So, like, we're talking about elements like boron, aluminum, gallium, indium, thallium, and so on. They're like the cool kids of the periodic table, hanging out in their own little group, causing some chemistry chaos.
The set difference is not commutative. This means that for two sets A and B, the expression A \ B is not necessarily equal to B \ A. In fact, A \ B contains elements in A that are not in B, while B \ A contains elements in B that are not in A, leading to different results unless A and B are identical.

The term abelian is most commonly encountered in group theory, where it refers to a specific type of group known as an abelian group. An abelian group, simply put, is a commutative group, meaning that when the group operation is applied to two elements of the group, the order of the elements doesn't matter.For example:Let G be a group with multiplication * or addition +. If, for any two elements a, b Є G, a*b = b*a or a + b = b + a, then we call the group abelian.There are other uses of the term abelian in other fields of math, and most of the time, the idea of commutativity is involved.The term is named after the mathematician, Niels Abel.
