Who established atomic number as the basic for organizing the periodic table?
Henry Moseley established atomic number as basis of periodic table.The properties of elements are periodic function of their atomic number.
1 iu is equal to how many mg?
The international unit varies according to the substance. An IU is the amount of something that is needed to produce an effect which has been agreed upon as a standard. So, 1000 IU of Vitamin D has a different mass than 1000 IU of Vitamin C.
What is anhydrous basis?
Anhydrous basis refers to expressing the concentration of a substance without considering any water present in the sample. It is commonly used in chemistry to provide a more accurate representation of the actual concentration of the substance of interest. By expressing values on an anhydrous basis, any water content in the sample is excluded from the calculations.
Who established atomic number as the basis for organizing the periodic table?
The concept of using atomic number as the basis for organizing the periodic table was established by Henry Moseley, an English physicist, in 1913. Moseley's work helped to refine the periodic table and provided a more accurate understanding of the arrangement of elements based on their atomic structure.
Why was basis of classification of element in the periodic table changed from atomic mass to atomic number?
Mendeleev's periodic table was based on the atomic masses of elements. However, this was not effective when isotopes were discovered. An isotope of an element is defined as the element having the same atomic number but varying mass numbers. So, mass numbers weren't constant and hence, a better characteristic was chosen -atomic number. Atomic number of any element was a characteristic of a particular element. Hence atomic numbers were taken as the basis of classification instead of atomic masses.
What letters A B C G does not represent one of the possable basis in the DNA structure?
The letter B does not represent one of the possible basis in the DNA stucture. The letters A represent Adenine, G represent Guanine , C represent Cytosine and the 4th is T for Thymine.
What are basis vectors in a transform?
Basis vectors in a transform represent the directions in which the coordinate system is defined. They are typically orthogonal (perpendicular) to each other and have unit length. These basis vectors serve as building blocks to represent any vector in the space.
Device used as the basis for time?
Atomic Clock -Eryl Paez
Difference between assay as is basis and dried basis?
Assay on 'as is' basis refers to the composition of a substance including its water content, while assay on 'dried' basis refers to the composition of a substance after removing the water content. Comparing these two types of assays can help in understanding the true chemical composition of a substance excluding the influence of water content.
What did Aristotle contribute to the atomic theory?
Aristotle rejected the concept of atoms and instead proposed a continuous, indivisible substance as the basis of all matter. His views on the composition of matter were influential for many centuries, until the development of modern atomic theory in the 19th century.
Who established atomic number as the basic for organizing the periodic table?
Henry Moseley established atomic number as basis of periodic table.The properties of elements are periodic function of their atomic number.
What is the basic theme of organisation in the periodic table?
to oragnise elements on the basis of atomic number.
What is the reason one can determine the number of electrons from the atomic number?
It is because atomic no. is decided on the basis of no. of protons in the atom and no. of protons is equal to no. of electrons in an atom.
Which fundamental property of the elements is the basis of modern periodic table?
Atomic number is the fundamental property. Elements are arranged in order of increasing atomic number.
1 iu is equal to how many mg?
The international unit varies according to the substance. An IU is the amount of something that is needed to produce an effect which has been agreed upon as a standard. So, 1000 IU of Vitamin D has a different mass than 1000 IU of Vitamin C.
Who was the first to set the atomic numbers as the basis for the organization of the periodic table?
Mosely, a british chemist
What is the basis of Mosley's periodic table?
Moseley arranged the elements according to increasing atomic number.
