What else can I help you with?
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.
What are two sets with the same number of elements called?
Two sets with the same number of elements are called "equinumerous" or "equipollent." This means there is a one-to-one correspondence between the elements of the two sets, allowing for a direct pairing without any leftover elements in either set. If the sets are finite, they have the same cardinality, which is the term used to describe the number of elements in a set.
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?
Disjoint means they have no elements in common. The union is the set of elements containing all elements from both sets. Since there is no overlap, the union will have 5+7 elements. Therefore the answer is 12.
Who grouped the elements into sets of three?

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.

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.
Are equivalent sets equal?
No, equivalent sets are not necessarily equal. Two sets are considered equivalent if they have the same cardinality, meaning they contain the same number of elements, regardless of the actual elements within them. For example, the sets {1, 2, 3} and {a, b, c} are equivalent because both have three elements, but they are not equal since they contain different elements.

Can an empty space be left in a three set venn diagram?
Yes, an empty space can be left in a three-set Venn diagram. This occurs when there are elements that do not belong to any of the three sets being represented. In such cases, the empty space indicates the absence of any overlapping or shared elements among the sets. It effectively highlights the distinctions between the sets and their unique characteristics.
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
