The elements in the Periodic Table are first arranged by atomic weight, then were grouped vertically by similar characteristics and traits. See:
http:/en.wikipedia.org/wiki/Group_(periodic_table)
Where it notes:
"The periodic table groups are as follows (in the brackets are shown the old systems: European and American):
- Group 1 (IA,IA): the alkali metals or lithium family
- Group 2 (IIA,IIA): the alkaline earth metals or beryllium family
- Group 3 (IIIA,IIIB): the scandium family
- Group 4 (IVA,IVB): the titanium family
- Group 5 (VA,VB): the vanadium family
- Group 6 (VIA,VIB): the chromium family
- Group 7 (VIIA,VIIB): the manganese family
- Group 8 (VIII, VIIIB): the iron family
- Group 9 (VIII, VIIIB): the cobalt family
- Group 10 (VIII, VIIIB): the nickel family
- Group 11 (IB,IB): the coinage metals (not an IUPAC-recommended name) or copper family
- Group 12 (IIB,IIB): the zinc family
- Group 13 (IIIB,IIIA): the boron family
- Group 14 (IVB,IVA): the carbon family
- Group 15 (VB,VA): the pnictogens or nitrogen family
- Group 16 (VIB,VIA): the chalcogens or oxygen family
- Group 17 (VIIB,VIIA): the halogens or fluorine family
- Group 18 (Group 0, VIIIA): the helium family/neon family; for the first six periods, these are the noble gases"

In the periodic table what is a period?
A period on the periodic table is a row.This is the horizontal section of the periodic table.
Where is pg on the periodic table?

What the is an anion and where can you find it in the periodic table?
periodic table
What is coal in its periodic table?
Coal is not on the periodic table.
Where are transition metals located in the periodic table?
Transition metals are located in group 3-12 of the periodic table. The middle of the periodic table.
Is the periodic table sorted by atomic number?
yes it is.
How can you find an element?
I'm assuming you mean "how can you find an element on the periodic table?" The periodic table is strategically placed. You can either look for the atomic number (the number at the top-- the number of the protons in one atom), or you can just look for the Element Symbol. The periodic table from left to right is sorted by increasing atomic number. The periodic table from top to bottom is sorted by increasing number of energy levels (the levels in which the electrons are in).
How is mosley's basics for arranging the elements different from mendeleeve's?
Dmitri Mendeleev created and sorted the periodic table by atomic mass. When years later Mosley rearranged the table and sorted it by Atomic number.
Why was mendeleev's periodic table valid at all?
His table was sorted by atomic mass, not atomic number. (the way today's periodic table is sorted) Mendeleev was almost right, but they did not know about protons at the time. (atomic number is the number of protons in an element) There would have been absolutely no way of him figuring out they were related to atomic number if he didn't even know about atomic number
How was moseleys periodic table arranged?
Compared to Mendeleev's periodic table which was arranged my atomic mass, Moseley's was, however, arranged by atomic number.
What is the name of the table of elements?
A Periodic table The Periodic Table of the Elements.
How are the elements arranged?
atomic number
What did Henry mosley do?
Henry Moseley sorted the chemical elements on the Periodic Table in order by their atomic numbers. Moseley was a British chemist who had studied under Rutherford.
What is a group in a periodic table.?
A group in Periodic Table is the column of element in periodic table
How is the Periodic Table used as a tool to study chemistry?
A periodic table is used to sort the 114 elements known to man. It is sorted in groups (alkalis, halogens, noble gases) and according to the number of electrons the elements have.
What is a chart that lists all the known elements?
It is called the Periodic Table of Elements.
Is snow on the periodic table?
No, it is not on the periodic table.
