It is organized by the number of electrons and the number of neutrons. so take gold for example the atomic number is 79 that means it has 79 neutrons so it is placed in between platinum and Mercury. Hydrogen is first because it only has one neutron in its nucleus and one electron.
The columns are arranged by family as they all tend to react the same way. The rows are organized by the number of electron orbitals they have.
to make room for new elements
-to classify them in terms of their behavior
-for easy recognition of elements
-so the (period) and the (groups) would align
it is set out in groups (columns) that group elements with similar properties and periods (rows) that are the number of electron shells in each element
its made up of rows and columns.there are 18 columns.
because it is sorted by the items the are abbreviated for.
The modern Periodic Table is arranged in the increasing order of their atomic number and repeating chemical / physical properties.
look on the periodic table
Look for the predictable changes and patterns.
Nonmetals are to the right of the metalloids on the periodic table.
just look at the periodic table
Yes depending on which scientists version of the periodic table you look at. Henry Moseleys ideas on the periodic table was the first to increase by atomic number.
In more than 150 years the periodic table had many versions; hundred versions of this table are known. The sole official table is today the IUPAC Periodic Table.
You look at the periodic table.
Yes it is! look at the Periodic Table
Look at the Periodic Table.
Lithium, just look at the periodic table.
The periodic table is arranged by the Atomic Number
i don't know maybe yu should look some else
look at a periodic table
look on the periodic table
Look for the predictable changes and patterns.
There are many patterns on the Periodic Table! They are in order by family, class, and atomic number. If you look up the periodic table, you will most likely find many more!
Nonmetals are to the right of the metalloids on the periodic table.
