Periods in the Periodic Table refer to the horizontal rows, while groups refer to the vertical columns. Elements in the same group have similar properties because they have the same number of valence electrons. Elements in the same period have different properties because they have different numbers of electron shells. The periodic table organizes elements based on their properties, with elements in the same group sharing similar characteristics.
Periodic patterns and trends
Chemists began organizing elements by noticing patterns in their properties. Dmitri Mendeleev created the first periodic table in the 1860s by arranging elements in order of increasing atomic weight and grouping elements with similar properties together. This laid the foundation for the modern periodic table.

The relationship between elements and periods according to the periodic law is that elements are arranged in periods based on their atomic number and properties. Elements in the same period have the same number of electron shells, while elements in the same group have similar chemical properties.
Dmitri Mendeleev discovered the periodic law and created the first version of the periodic table of elements, organizing known elements by increasing atomic mass and predicting properties of undiscovered elements.

The periodic law proposed by Dmitri Mendeleev states that the properties of elements are periodic functions of their atomic weights. Mendeleev used this law to create the first periodic table of elements, predicting the properties of missing elements and organizing them based on their atomic weights and chemical properties.

The periodic table allows us to understand why the chemical elements have the properties that they have. It is the most basic organizing principle in chemistry.
Henry Moseley established atomic number as basis of periodic table.The properties of elements are periodic function of their atomic number.
Dmitri Mendeleev is the chemist credited with developing the periodic table in 1869. His arrangement of elements by atomic mass and chemical properties formed the basis for the modern periodic table.
The relationship between elements and periods according to the periodic law is that elements are arranged in periods based on their atomic number and properties. Elements in the same period have the same number of electron shells, while elements in the same group have similar chemical properties.
Mendeleev's periodic table was confirmed to be useful because it accurately predicted the properties of elements that had not been discovered at the time. When new elements were discovered and found to fit into the gaps Mendeleev had left, it provided strong evidence for the effectiveness of his periodic table in organizing elements based on their properties. This confirmed the periodicity of elements and highlighted the power of the periodic table as a tool for understanding and predicting the behavior of elements.

The periodic table was developed by Russian chemist Dmitri Mendeleev in 1869. He arranged the elements based on their atomic mass and chemical properties, revealing repeating patterns in their behavior. Mendeleev's periodic table is a fundamental tool in chemistry for organizing and predicting the properties of elements.
Mendeleev's periodic table allowed for the prediction of the properties of unknown elements by identifying gaps in the table where elements had not yet been discovered. By examining the properties of neighboring elements, Mendeleev was able to predict the properties of the missing elements and suggest their existence. His periodic table provided a framework for organizing elements based on their atomic mass and chemical properties, which allowed for the accurate prediction of the properties of undiscovered elements.
