They are organized according to atomic number, which refers to the number of protons that the nucleus contains. They are organized into columns, called families by the number of electrons in the orbitals. The farther down you go, the more elements, because there are more orbitals on higher energy levels. Also, the elements to the right of the line on the periodic table are nonmetals, the ones on the line are semimetals, and the ones to the left of the line are metals.
Elements are grouped together on the Periodic Table based on similar chemical properties and electron configurations. This organization allows scientists to predict the behavior of elements based on their placement in the table. The periodic table also shows trends in properties such as atomic size, ionization energy, and electronegativity within each group and period.

Elements are arranged by atomic number in the what?
Elements are arranged by atomic number in the periodic table. The atomic number represents the number of protons in the nucleus of an atom. This arrangement allows elements with similar properties to be grouped together in columns called groups or families.
What was the first periodic table?
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
Is the Periodic table a chart of compounds grouped according to their properties?
No, the periodic table is a chart of elements arranged by their atomic number and chemical properties, not compounds. It provides information on elements' atomic structure, such as their electron configuration and reactivity, rather than compounds formed by combining elements.
What physical property did Mendeleev use to places the element in rows on the periodic table?
Mendeleev used the increasing atomic mass of elements to arrange them in rows on the periodic table. This allowed for elements with similar properties to be grouped together and for the gaps to be left for undiscovered elements.
What is the similarities in the modern periodic table and Mendeleev's table?
Both the modern periodic table and Mendeleev's table are organized by increasing atomic number and similar properties are grouped together. They both have periods (rows) and groups (columns) that showcase trends in atomic properties. Additionally, both tables provide a systematic way to predict the properties of elements based on their position.
How elements are grouped in columns in the periodic table?
There are 18 groups in the Periodic Table of elements.
What are elements on the periodic table are grouped based on?
Group are based on similar properties. The elements having same chemical properties are grouped together.
What are the properties based on modern periodic table?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
Why it was needed to develop the periodic table?
The elements with same properties need to be grouped together. So that it is easier to study the elements
The type of element grouped on the left side of the periodic table is the?
Metals are grouped together to the left of the Periodic table.
How are the properties displayed in the periodic table?
Elements with same property are grouped together. Property can be estimated by its position.
What is one way scientists have grouped elements?
the Periodic Table of elements
What does the periodic table show us about atoms of various elements?
Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.
What did Dmitri Mendeleev discover?
he drew up a table that grouped elements according to their atomic weights, his table became the basis for the periodic table of elements used today.
What was the name of the first scientist who grouped the elements an the periodic table?
MOSLEY
What type of elements are grouped on the left side of the periodic table?
Metals
Elements are arranged by atomic number in the what?
