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?

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.


How do you determine if number sets same or different?

To determine if number sets are the same, compare their elements to see if they contain exactly the same numbers, regardless of order or repetition. If each number in one set can be matched to a number in the other set without any discrepancies, the sets are the same. If there are any differing elements or counts of elements, the sets are different. Using a method like sorting the sets or converting them to a list of unique elements can help in this comparison.

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.

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.

How many subsets can be made from a set with 6 elements?

Well, honey, I hope you're ready for this math lesson. A set with 6 elements can have 2^6, which is 64 subsets. That's right, 64 ways to slice and dice those elements. So, grab a calculator and start counting, darling!
