Modern periodic law: The Modern periodic law states “ The chemical and physical properties of elements are a periodic function
How do you explain periodic law?
The Periodic Law states that the physical and chemical properties of the elements recur in a systematic and predictable way when the elements are arranged in order of increasing atomic number. Many of the properties recur at intervals.
Who define modern periodic law?
Dmitri Mendeleev and Lothar Meyer gave the Modern Periodic Law. Complete step by step answer: We can start this answer with the definition of Modern Periodic Law. The Modern Periodic Law can be stated as: “The physical and chemical properties of the elements are periodic functions of their atomic numbers”.
What is the basis of modern periodic law?
Complete answer:
In placing atomic atoms, then after a predictable period, identical electronics are performed. According to the increasing atomic number, Z, elements are therefore arranged in the periodic table . This is the basis of the Modern Periodic Law.
What does Mendeleev’s periodic law state?
the law that the properties of the elements are periodic functions of their atomic numbers . Also called Mendeleev’s law. (originally) the statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights.
What is the periodic law simple definition?
: a law in chemistry: the elements when arranged in the order of their atomic numbers show a periodic variation of atomic structure and of most of their properties .
What causes periodic law?
Periodic trends arise from the changes in the atomic structure of the chemical elements within their respective periods (horizontal rows) and groups in the periodic table . These laws enable the chemical elements to be organized in the periodic table based on their atomic structures and properties.
What is modern periodic law explain with examples?
The modern periodic law states that the physical and chemical properties of the elements are the periodic functions of their atomic numbers . Scientists arranged elements in increasing order of their atomic numbers from left to right across each row.
What are the use of modern periodic table?
The modern periodic table is used to organize all the known elements . Elements are arranged in the table by increasing atomic number. In the modern periodic table, each element is represented by its chemical symbol. The number above each symbol is its atomic number.
What are the advantages of modern periodic table?
- It is easier to remember the properties of an element if its position in the periodic table is known.
- The periodic table has made the study of chemistry systematic and easy. ...
- The type of compounds formed by an element can be predicted by knowing it position in the periodic table.
What is the basis of modern periodic table Class 10?
Mendeléev’s Periodic Law was revised taking atomic number as the basis of Modern Periodic Table. Modern Periodic Law can be stated as ‘Properties of elements are a periodic function of their atomic number. ‘
What is Monday leave periodic?
This means that the physical and chemical properties of elements depend on their atomic weight such that on arranging elements in increasing order of atomic weight, elements with similar properties are repeated after regular intervals of increasing atomic weight. 4 (40)
What is the basic difference between Mendeleev periodic law and modern periodic law?
| Mendeleev’s periodic table Modern periodic table | There are a total of 7 groups and 6 periods There are a total of 18 groups and 7 periods. | Elements are arranged based on their increasing in atomic mass Elements are arranged based on the increasing order of their atomic numbers. |

What was Mendeleev’s periodic law class 10?
Mendeleev’s Periodic Law: It states that “ the properties of elements are the periodic functions of their atomic masses .” It means the properties of the elements depend on their atomic masses and the elements are given a position in the periodic table on the basis of their increasing atomic masses.
What is periodic law states?
The periodic law states “ When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties .”
How important is the periodic law?
In fact, the periodic table is so accurate that it allows scientists to predict the chemical and physical properties of elements that hadn’t yet been discovered . ... “The elements, if arranged according to their atomic weights, exhibit an apparent periodicity of properties,” said Mendeleev.
