Mendeleev's Periodic Table -- the reason for periodicity -- is explained by the arrangement of the electrons around the nucleus.

In Groups 1 and 2, the atomic numbers increase from top to bottom as you move down the group. In Groups 13 to 18, the atomic numbers also increase from top to bottom within the group. Groups 1, 2, and 13 to 18 are also known as the representative elements.

What statement says that the properties of elements repeat in predictable way when atomic numbers are used to arrange elements into groups?
The periodic law states that the properties of elements repeat in a predictable way when elements are arranged in order of increasing atomic number into groups with similar properties.
What are the elements in the periodic table based on?
Atomic Number
The periodic law states that the properties of elements will repeat when the elements are arranged by _______.?
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
In the periodic table the elements are arranged in order of increasing?
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.
What is the modern periodic table based on?
The modern periodic table is based on the atomic number of elements, which is the number of protons in the nucleus of an atom. Elements are arranged in order of increasing atomic number, which helps to group elements with similar properties in columns called groups or families.
What data about elements are found on the Periodic Table?
On standard ones, Their Symbols, atomic & mass numbers, and groups.
Elements are organized in the periodic table by their?
Elements are organized in the periodic table by their atomic number, which represents the number of protons in the nucleus of an atom. The atomic number determines the unique properties of each element, and elements with similar properties are grouped together in columns called groups.
What statement says that the properties of elements repeat in predictable way when atomic numbers are used to arrange elements into groups?
The periodic law states that the properties of elements repeat in a predictable way when elements are arranged in order of increasing atomic number into groups with similar properties.
How elements arranged in the periodic table?
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
How are the elements arranged?
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.
What is the periodic law?
Periodic Table of elements.
The elements in the periodic table goes accoring to?
In the modern form of periodic table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.
How are period arranged on the periodic table?
The elements are arranged in order of increasing atomic number in the Periodic Table. The rows are called periods and the columns are called groups.
How are elements organized?
atomic number Chemical elements are organized in the form of the periodic table of Mendeleev, in groups and periods.
Is your modern periodic table based on atomic mass or atomic number?
The modern periodic table is arranged according to the elements' atomic numbers.
What are the elements in the periodic table based on?
Atomic Number
What are the order of elements on the periodic table based on?
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
