Yes they are.
atomic numbers
In the periodic table, the elements are arranged in order of increasing atomic number from left to right and top to bottom. This arrangement allows elements with similar chemical properties to be grouped together in columns known as groups or families.
Mendeleev arranged the elements in order of increasing atomic mass.Moseley arranged the elements in order of increasing atomic number.
No. The elements are arranged in order of increasing atomic number.
Henry Moseley arranged the elements in order of increasing atomic number rather than increasing atomic mass, which led to the modern periodic table.
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
Elements are arranged in order of their Proton Number/Electron Number. they are NOT arranged in Atomic Mass , because a given element my have isotopes, which alters the Atomic Mass.
The elements are arranged in the increasing order of their atomic number and repeating properties.
The Modern Periodic Law states that there will be a periodic repetition of properties when the elements are arranged according to increasing atomic number.
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
The elements on the periodic table are arranged in order of increasing atomic number.
Elements on today's periodic table are arranged by increasing atomic number, with elements sharing similar chemical properties placed in the same column (group). The table is divided into metals, nonmetals, and metalloids, and elements are organized by their electron configuration and reactivity. The periodic table is a powerful tool for predicting the properties of unknown elements and understanding their relationships.
