The columns of the periodic table are called groups (or families). All elements in a group have the same number of electrons in their outer orbital. Furthermore, since many chemical properties are determined by the location of the outermost electrons, elements in the same group will share many common properties.
The columns of the Periodic Table, known as groups, indicate elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which influences their reactivity and bonding characteristics. This organization helps identify patterns in the behavior of elements and predict their properties.
Rows (Periods) on the Periodic Table tell you how many electron shells are in an atom of that elemnt. The further down you go in the Periodic Table, the more electron shells there are. It goes in an ascending order, the first period of elements have 1 electron shell, the second period 2 electron shells, the third 3 shells and so on.
the horizontal rows are called periods the vertical columns are called groups A periodic table is a tabular display of the chemical elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties. Elements are presented in order of increasing atomic number.
Groups or families. Each column represents elements with similar chemical properties, due to the number of valence electrons they have.
The s block is located on the left side of the periodic table, corresponding to groups 1 and 2. It includes elements like hydrogen, lithium, and sodium. These elements have one or two electrons in their outermost s orbital.
The columns are called "groups" while the rows are called "periods." Elements in the same groups share chemical properties, while those in periods share relative sizes of nuclei.
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.

Those are columns.
The main group of elements includes all the elements in columns 1, 2, and 13 through 18 of a wide form periodic table. All the other elements are "transition elements", and those in the two horizontal rows at the bottom of a wide form periodic table are also called "inner transition" 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.
Groups or families. Each column represents elements with similar chemical properties, due to the number of valence electrons they have.
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
The s block is located on the left side of the periodic table, corresponding to groups 1 and 2. It includes elements like hydrogen, lithium, and sodium. These elements have one or two electrons in their outermost s orbital.
The columns are called "groups" while the rows are called "periods." Elements in the same groups share chemical properties, while those in periods share relative sizes of nuclei.
Because those elements were not known when he formulated his periodic table.

The transition elements are located in the d-block of the periodic table, which includes groups 3 to 12. These elements have partially filled d-orbitals and exhibit a wide range of oxidation states and complex chemistry.
