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.
To determine the number of valence electrons, you look at the group number of an element on the periodic table.
There are currently 118 elements in the periodic table, with 20 man-made and 88 (not 92) naturally-occurring elements. *Since 23rd October 2008.
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.
The period of silver on the periodic table is Period 5. This means that silver's outermost electron shell is the fifth shell from the nucleus.
no because if you look back in time more they didn't know as much as we do now so we learn more over time so if you looked back in time you wold see that there would be gaps in random spots on the periodic table. :)
You look at the periodic table.
Yes it is! 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
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!
The periodic table may change over time as new elements are discovered or as our understanding of atomic structure evolves. New elements can be added to the table, and their properties may lead to a reorganization of the elements. The overall layout and concepts of the periodic table are likely to remain consistent, but the specific details can change.

The Periodic Table
The number one element on the periodic table is hydrogen. It is not a metal, but the lightest and most abundant element in the universe.
Look for predictable changes and patters.
The basic idea is that when arranged in a certain way (the way presented in the periodic table), elements in the same column tend to have similar properties.
