Dmitri Mendeleev, a Russian chemist, organized the periodic table in the manner that we know today. Initially, he organized them by increasing Atomic Mass, but that caused a few mis-matches. Later, he re-organized them by increasing atomic number, and it made more sense. His organizational skills helped us to predict the properties of elements unknown during his time. Turns out they fit right in where they should, upholding his brilliant creation.

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).
Why is the table of elements known as the periodic table?
Simply, the periodic table is set up by listing elements by their atomic number, or the number of protons in an atom's nucleus.
Why are things grouped together on the periodic table?
-An element is placed in that group of periodic whose group number is equal to the number of valence electrons.
How do you find the atomic number in the periodic table?
The atomic number of an element is the number of protons contained within the nucleus of an atom of that particular element. Since each element has a different number of protons, elements can be placed into a table based on the number of these particles.
What are the lanthanides placed on the perioic table?
Lanthanoids are placed down in the periodic table.They contain elements with atomic number 57 to 71.There are total 15 elements in lanthanoids group.
Why is hydrogen placed first in the periodic table?
Because It has 1 proton. The elements on the periodic table are order by the number of protons.
How does a new element get put on the periodic table?
The key defining characteristic between elements is the number of protons their atoms have. The periodic table is organized by increasing atomic numbers which are the number of protons each atom has. So a new element would be given an atomic number equal to the number of protons it has, then placed wherever it lands in numerical order with the all the existing elements.
What can you determine about an atom based on its Atomic Radius?
the further right you go on the periodic table, the atomic radius decreases. the further down you go on the periodic table, the atomic radius increases. you can determine where an atom is generally placed on the periodic table based on its atomic radius.

Where are the antinides on the periodic table?
Actinides comprise of atomic number 90-103. They are placed at bottom of periodic table.
The what are located in the center of the periodic table?
The transition metals are found toward the middle of the periodic table.
What periodic table number is 87?
Fr is the element having atomic number 87. It is placed in group-1 and period-7 of Periodic Table.
Was is the atomic number of iridium on the periodic table?
The atomic number of iridium is 77. Its symbol is Ir. It is placed in group-9 and period -6 in the periodic table.
