Elements are arranged into rows in order of increasing mass, so that elements with similar properties were in the same column. They are organized by type, such as nonmetals, metals, and metalloids, and solids, liquid, gas, or not found in nature.

∙ 14y agoThe Periodic Table is organized in rows and columns called Periods and Groups respectively. Each row (period) in the table corresponds to the filling of a quantum shell of electrons. The elements in a group have similar configurations of the outermost electron shells of their atoms (most chemical properties are dominated by the orbital location of the outermost electron). See http://knol.Google.com/k/spiros-kakos/periodic-table-of-elements/2jszrulazj6wq/88# for more details on the meaning of groups and periods.

Wha do each of the numbers in a box represent on the periodic table?
Each box on the periodic table represents a single element. :D
What element has a relative atomic mass of 15.5?
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
What is the answer for the formula NaCl in the periodic table of elements?
Table Salt. NaCl is the chemical formula for Sodium chloride. It is not on the periodic table because it isn't a chemical element. Sodium chloride is a chemical compound formed when the elements Sodium and Chlorine react with each other.
Where is the atomic number written?
The Atomic Number Is Located On The TOP Of The Element Symbol. So Example. 14<ATOMIC NUMBER> Si<Symbol> 28.086<Atomic Mass> Silicon <The Name> This Is The Correct Order Of An Element That Should Be Labeled.
Why isn't opal on the periodic table?
The periodic table of elements is only for, well, elements. A diamond is not an element, it is a mineral. An element is a compound or molecule that cannot be broken down into anything smaller, example: hydrogen, oxygen, even gold. Diamond isn't an element therefore it cannot be in the periodic table. It is a compound composed completely of Carbon, an element with atomic number 12. Graphite is also completely composed of Carbon yet is very different to diamond in its physical and chemical properties. i.e diamond is glassy, colourless and hard, graphite is dark grey/black and is soft. This has to do with the arrangement of the carbon atoms in each compound respectively. it is not a basic element. it is a byproduct of one.because diamond is a covalently bonded lattice of carbon atoms.the periodic table only lists elements and not compounds so diamond is not in this, carbon (the substance diamond is made from) is.
How is each elements placed on the periodic table?
Each element is placed according to the increasing order of their atomic number and repeating properties.
What is the number listed for each element on the periodic table?
The number listed above the symbol of an element on the periodic table is the element's atomic number.
Does each element have a unique name and formula on the periodic table?
Yes, each element on the periodic table has a unique name and chemical symbol.
What can you not find on the periodic table?
Isotopes of each element.
What does the periodic table tell you about the element in a group?
The groups in the periodic table tell you what each element within them will react with, the number of valance electrons the element has, and what family it is in.
Where are elements found on periodic table?
On the periodic table there are squares. Each square corresponds to one element.
How many Nurtons are there in the periodic table?
Each element on the periodic table has a specific number of neutrons and will vary for its isotope.
How many regions are there in the periodic table with in each element?
The periodic table of Mendeleev has 18 groups and 7 periods.
What information about an element can we get from each box on a periodic table?
somthing
How is each element represented in periodic table?
Each element is represented by a one or two-letter symbol.
How is each element in the periodic table represented?
Each element is represented by a one or two-letter symbol.
How are isotopes placed in the periodic table?
Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).
