the Periodic Table is grouped according to similarities. when Mendeleev grouped his first periodic table they followed a pattern. any elements that contained similarities they were all put into the same column.

∙ 13y agoElements in the periodic table are arranged in groups (vertical) and periods (horizontal). If a group of elements is in the same group it means that all the elements will react similarly when in the same circumstances and situations.
Then as you move from left to right across a period each element will have one more electron in its outer shell. The element on the end of a period will have a full outer shell of electrons. Basically they're arranged by their atomic number and Atomic Mass so each element has a higher atomic weight than the one on its left.
Note: The atomic number is the number of protons in the element's nucleus.
The atomic weight of each element is how heavy its atoms are in comparison to an atom of hydrogen which is the lightest element.

∙ 13y agoThere are 18 columns on the periodic table. The first 2, and 13-18 are all grouped by how many valence electrons the outermost ring of an atom has. Therefore, the elements in the columns all have similar properties. There are also other ways they are grouped. They are arranged in "number order". The number is how many protons are in the nucleus of the atom. And, they are also grouped by metals, non-metals and metalloids. The elements all the way to the left are considered "metals", some on the "staircase" are metalloids, and the ones all the way to the right are non-metals, or known as gases. The only exception to this rule is Hydrogen, it's a non-metal, but it's all the way to the left in the 1st column.

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
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.
What is the similarities in the modern periodic table and Mendeleev's table?
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
The table is called the periodic table because?
Because in the table the elements are arranged into "periods", elements belonging to the same period have similar physical/chemical properties. This in tern reflects the fact that they have a similar number of outer shell electrons.
How elements are grouped in columns in the periodic table?
There are 18 groups in the Periodic Table of elements.
What is one way scientists have grouped elements?
the Periodic Table of elements
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
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
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.
Where are the most reactive metals grouped in the periodic table of elements?
Group I, the Alkalai Metals
What is the periodic table of elements about?
The periodic table lists the elements that are currently known. They are grouped by atomic weight in most cases, by properties, and go in order by number of protons in the nucleus.
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.
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.
On the periodic table of elements what kind of gases are grouped in the far right column?
The answer is: noble gases
