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.

What was the importantance of mendeleeve's periodic table to chemists?
Mendeleev arranged elements in rows and columns according to increasing atomic masses. The elements with same properties were grouped together which formed the base for modern periodic table.
Is the Periodic table a chart of compounds grouped according to their properties?
there are no compounds on a periodic table. only elements are placed in the periodic table and they are grouped by similar attributes
Where are the most reactive metals grouped in the periodic table of elements?
Group I, the Alkalai Metals
Who is the father of the modern periodic table in chemistry?
Henry Moseley is father of modern periodic table. He arranged elements in order of increasing atomic number. He arranged elements such that the elements with same properties were grouped together.
Why are nitrogen and phosphorus are both in group 5 in the periodic table?
Because they both have 5 electrons in their outer shell. This is the way that the elements in the periodic table were grouped.
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.
