no. some are diffrent..
yes
If they are placed in the same vertical column, which is called a group, it means that they have similar properties. For example, the first column (group) of the periodic table are the alkali metals. The second is alkali earth metals. Other groups include halogens, royal gases, etc.
Three elements that have similar chemical properties to oxygen are sulfur, selenium, and tellurium. These elements belong to the same group as oxygen in the periodic table and have similar electron configurations, which influence their reactivity and chemical behavior. Additionally, they can form similar types of chemical bonds with other elements.
The elements in each column of the periodic table have generally similar chemical properties, except that in columns 8 through 10, the elements in each row are at least as similar to one another as those in the same columns in other rows.
a group of elements that have similar properties are arranged one on top of the other on the periodic table. These groups are also called families
The only elements that form an ion isoelectric with krypton are the elements in Period 4 and Columns 15 through 17 of a wide form periodic table and the elements in Period 5 and Columns 1 and 2 of a wide form periodic table. All other elements do not form such an ion.
Physical and chemical properties change somewhat regularly across a period. Elements that are close to each other in the same period tend to be more similar than elements that are father apart.

The rows going across the periodic table are called periods. As you go across a row, each element increases in number of protons and electrons, which distinguishes it from other elements in the table.

The periodic table was not 'identified.' It is simply all known elements ordered by similar qualities and atomic number, among other things.
Na (sodium) belongs to the first group (vertical row) in the periodic table, all of the other elements in this group (row) have similar characteristics to each other. In general, each group has similar characteristics.
They will be in the same group (for example the halogens and noble gases). Look at the periodic table.
The elements of the periodic table are grouped and organized together based on similar characteristics. These include their atomic number, chemical families (halides, noble gases, metals, gases, transition elements) and nuclear sizes, among other factors.
