They have different numbers of valance electrons...
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.
The groups on the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. The periodic period of elements refers to the horizontal rows on the periodic table, which indicate the number of electron shells an element has. Elements in the same period have the same number of electron shells, but elements in the same group can be in different periods.
Elements with similar chemical properties are found in the same group on the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical behavior. Elements in the same period have different numbers of electron shells, leading to varying chemical properties.
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.
True. Elements with similar properties are typically found in the same group (vertical column) on the periodic table due to a similar arrangement of their outer electrons and valence shell. Elements in the same period (horizontal row) have different properties but share the same number of electron shells.
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
no. A period is a row of elements in the periodic table whose properties change gradually and predictably.

They change with atomic number.
They have similar chemical properties.
True. Elements with similar properties are typically found in the same group (vertical column) on the periodic table due to a similar arrangement of their outer electrons and valence shell. Elements in the same period (horizontal row) have different properties but share the same number of electron shells.
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
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.
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.
