What do you called the arrangement of grouping elements by three?
This arrangement is called "triplets," where elements are grouped in sets of three.
Why did Johann dobereiner trying to order the elements?
Johann Dobereiner attempted to order the elements to find patterns and relationships between their properties. He proposed the Law of Triads, which grouped elements with similar properties into sets of three based on their atomic weights. This was an early attempt at organizing the elements before the more comprehensive periodic table was developed.
What is the limitation of dobereiners periodic table?
All the elements known at that time could not be arranged as Dobereiner's triad's example: the three elements, nitrogen, phosphorus and arsenic have similar properties. Therefore they can be regarded to form a triad. However, the actual atomic mass if the middle element, phosphorus(P)(31.0u)is much lower than the average or mean(44.45u)of the atomic masses of nitrogen and arsenic. Thus, these three elements do not constitute a Dobereiner triad in spite of their similar chemical properties.
If A and B are disjoint sets and A contains 5 elements and B contains 7 how many elements are in the union of A and B?
The union of two disjoint sets is the combination of all elements contained in both sets. Since A and B are disjoint, their union will contain all elements from A and B without repetition. Thus, the union of A and B will contain 5 + 7 = 12 elements.
What sets of elements have similar physical and chemical properties?
Except noble gases the groups of elements in periodic table have the similar chemical properties but not the physical.
Who grouped the elements into sets of three?
Dmitri Mendeleev

What is the purpose of the overlapping section in a Venn diagram?
The overlapping sections show elements that belong to each of the two (or maybe three) sets that overlap there.The overlapping sections show elements that belong to each of the two (or maybe three) sets that overlap there.The overlapping sections show elements that belong to each of the two (or maybe three) sets that overlap there.The overlapping sections show elements that belong to each of the two (or maybe three) sets that overlap there.

How many subsets can be made from a set with 6 elements?
If a set has six elements, for example {A, B, C, D, E, F}, then it may have the following subsets: - the set itself - 6 sets of five elements - 15 sets of four elements - 20 sets of three elements - 15 sets of two elements - 6 sets of one element - 1 set with no elements (the null set), for a total of 64 sets, which is 2^6, or 2 to the 6th power.

What are equal and equivalent sets?
Equal sets contain identical elements. e.g. if A = {1,2,3} and B = {1,2,3}, then A and B are equal - their elements are the same. Equivalent sets have identical numbers of elements. e.g. if A = {1,2,3} and B = {a,b,c}, then A and B are equivalent - they both have three elements.
Which of these observations led to the law of triads?
The observation that groups of three elements had similar properties and atomic weights led to the development of the law of triads by Johann Dobereiner in early 19th century chemistry. This law suggested that elements could be grouped into sets of three with similar characteristics where the atomic weight of the middle element was roughly the average of the other two.
What is a graph that shows the relationships between two sets of data?

What is it when you have all the elements in two or more sets?
The set of elements that are elements of the two (or more) given sets is called the intersection of the sets.
What is equal set from equivalent sets?
equal sets with exactly the same elements and number of elements.equivalent sets with numbers of elements
Relationship of elements and subsets?
Elements can belong to subsets. Subsets can be elements of sets that are called "power sets".
