display of the elements in order of atomic number with similar elements falling into columns.

A matrix in which the elements are arranged across rows in order of increasing atomic number so that elements with similar chemical properties fall in the same vertical column.

The periodic table is an arrangement of all the elements. The elements are listed in order of increasing atomic number. Elements listed in the same column on the periodic table have the same number of valence electrons and have similar properties while elements in the same row on the periodic table (called periods) all have the same valence shell. Each box on the periodic table contains information including the elemental symbol, the atomic number, and the average mass in amus of one atom of the element.

a chart that groups the elements by similar properties and structures

an arrangement of elements into rows and columns according to similarities in their properties.

A systematic arrangement of the elements in columns and rows; elements in a given column have similar properties.

A chart that lists all of the known elements.(Basic Science/Electricity/elements.htm)

The list of naturally occurring elements in order of increasing mass.

The Periodic table is a chart used primarily by chemists. It summarises the elements by arranging them in the order of their atomic number in such a way that similarities and trends can be appreciated. Each row (or PERIOD of the table) exhibits a range of properties that can be interpreted by how the electron orbitals of the atom are filled. Each column or GROUP of elements exhibits similar properties (like a family show similar characteristics).

Periodic table is a table of the elements, written in sequence in the order of atomic number or atomic weight and arranged in horizontal rows (periods) and vertical columns (groups) to illustrate the occurrence of similarities in the properties of the elements as a periodic function of the sequence. The original form was proposed by Dmitri Mendeleev (1834-1907) in 1869 using relative atomic masses.

A table that lists the elements in order of increasing atomic number.

a tabular arrangement of the chemical elements according to atomic number as based on the periodic law

a great tool for finding information about and teaching about the elements

the chart or list of all the elements.

Grouping of the known elements by their number of protons. There are many other trends such as size of elements and electronegativity that are easily expressed in terms of the periodic table.

An ordered table of all the elements arranged by their atomic numbers, i.e., the number of protons and electrons in an atom. The arrangement means that elements with similar properties are grouped near to each other.

an organization of all the elements, in a manner that show some major properties and similarities

Early alchemists understood that certain elements could be grouped together due to the properties that they had. But it was not until the 18th century that Lavoisier tried to classify the known elements. It took another 100 years and a lot of trial and error for Mendeleev to propose a real foundation for the modern periodic table. He arranged the elements in a table according to relative atomic mass and left gaps where an element did not match. By doing this he could predict where a new element should come and what properties it should have.

An arrangement of chemical elements based on the periodic law.

The periodic table is a chart of all the known elements in order of increasing atomic number. The table puts elements into groups with similar characteristics, allowing us to recognize trends over the whole array of elements. ( www.studyisland.com) a table in which the elements are commonly arranged in order of increasing atomic number. Elements of similar properties are placed one under the other, yielding eight families or groups of elements. Within each group there is a gradation of chemical and physical properties, but in general a similarity of chemical behavior. From group to group, however, there is a progressive shift of chemical behavior from one end of the table to the other. www.hach.com/cs/csglosy.htm

The arrangement, by atomic number, of elements into groups with similar chemical properties.

a chart showing all the elements arranged in columns in such a way that all the elements in a given column exhibit similar chemical properties.

a table of the tlements in order of increasing number and grouped according to their shared similarities

An arrangement of elements in order of increasing atomic numbers that also emphasizes periodicity.

An arrangement of the elements according to increasing atomic number that shows relationships between element properties.

The chart where all the elements are arranged so that those with similar chemical properties are in the same column.

An arrangement of the elements according to their atomic numbers so that elements with similar properties are in the same column. The first periodic table was published by Dmitri Mendeleev in 1869. The symbols of some elements are derived from their Latin names (in parentheses). Chemical element Symbol Atomic number

Table that describes some of the chemical properties of the known elements.

Arrangement of the chemical elements by atomic number, starting with hydrogen in the upper left-hand corner and continuing in ascending order from left to right, arranged in columns according to similar chemical properties.

The alternative table is a standard periodic table rotated counterclockwise and then mirrored across the vertical axis, hence like in many writing systems, the lower groups are to the left and the number increases to the right. Due to the rotation and the incorporation of the lanthanides and actinides into the main table, the Alternative Table is significantly longer vertically than the Standard Table. Its restricted width allows it to be read on-line without having to scroll horizontally.

The large version of the periodic table set out below does not fit into some computer screens; however, with a small font size and/or in landscape mode, it may be possible to print this periodic table on one or two normal-size sheets of paper. The key below explains the color-coding and layout of each entry.

This extended periodic table was suggested by Glenn T. Seaborg in 1969. It is a logical extension of the principles behind the standard periodic table to include as-yet-undiscovered chemical elements.

This is a standard display of the periodic table of the elements.

The text-only table is a version of the large table designed for printing atomic mass data. Colors representing chemical series have been removed, and all links have been removed. The least significant digit has been dropped if its uncertainty is greater than 1.
