Depending on the block it may be increasing or decreasing acidity, atomic radii varies through periods, atomic number increases by 1 with each element, ... as to reactivity, elements of lower periods are almost all radioactive, as with a heavier nucleus nuclear stability decreases. Hope this answers your question! :D
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
They change with atomic number.
The Periodic table is a representation of all elements grouped in a manner that lists elements with similar properties in columns. Adjacent columns have deceasing or increasing characteristics
Group 3 and period 6 of the modern periodic table contains elements from the lanthanide series, also known as the rare earth elements. These elements are characterized by their similar properties and placement below the main body of the periodic table.
A period on the periodic table is a horizontal row of elements that share similar properties. It helps organize the elements by arranging them in order of increasing atomic number and grouping elements with similar chemical properties together.
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
no. A period is a row of elements in the periodic table whose properties change gradually and predictably.
The rows in periodic table are known as periods. The arrangement is such that elements with similar properties fall in the same period.
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
A period in the periodic table is a horizontal row of elements that share similar chemical properties. Each period represents the number of electron shells in an atom. The organization of elements into periods helps to show trends in properties as you move across the table from left to right.
They have similar chemical properties.

The periodic table is a system for classifying the elements based on their atomic number, electron configuration, and chemical properties. It groups elements with similar properties together in rows and columns.
Periodic means repeating. When Mendeleev was rearranging the elements, he noticed that some of their properties matched with one another about every eight elements. Thus, when the elements are arranged in the rows of the Periodic Table, they also have matching properties in each column.
