It is arranged such that similar elements with similar preferred bonding arrangements are aligned vertically. This exposes the various s, p, d, and f bonding orbitals for each successive "exterior" shell, and so appears to repeat... hence "periodic".
The Periodic Table is called such because it is arrangened into periods. The rows of the table are called periods while the columns are called groups.
The reason why the periodic table is called so is because the rows are arranged in periods which helps to tell their properties
It is called the periodic table because elements separated by a fixed difference in atomic number (period) have similar properties.
Columns in the periodic table are called "groups" and there are 18 groups in the periodic table.
a horizontal row is called a period.a vertical row is called a group
The vertical columns on the periodic table are called groups or families.
The horizontal rows on the periodic table are called periods.
The columns on a periodic table are called groups. I hope that answers your question.
The elements arranged according to their atomic number in the table are called periodic table.
15 (the 15th column from the left) or also called 5A on some periodic tables.
A Periodic table The Periodic Table of the Elements.
Because the elements that have similar properties are arranged in groups - or 'periods'.
Periodic table (Mendeleev table) of the chemical elements.
7The Periodic Table has 7 periods and 18 groups.
The Periodic Table for Chemistry is as important as times tables for Maths.
In the periodic table only the chemical elements appear; but tables for isotopes also exist.
In a column that is numbered 16 on most "extended form" tables or VI(A) on "narrow form" tables.
It is called the Periodic Table of Elements.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
The rows on the periodic table are called periods
