Around the same time as Dmitri Mendeleev's publication of his Periodic Table in 1869, other scientists, including Lothar Meyer, were also developing their own versions of the periodic table. Meyer created a similar table that organized elements by atomic volume and chemical properties. Additionally, John Newlands proposed the Law of Octaves in 1865, which also aimed to classify elements based on their properties. However, Mendeleev's table is the most recognized for its predictive power and organization.
What else can I help you with?
What are characteristics of periods in the periodic table?
Periods have same shells. There are 7 periods in periodic table.
What is the definition of block in periodic table?
In the periodic table elements having valence electrons in the same orbital are said to be placed in the same block.There are four blocks in the periodic table s, p, d and f.
What does elments found in the same family on the periodic table have in common?
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
What do atoms of the same elements in the same group of the periodic table have in common?
They are the same
Do the element in the periodic table have the same atomic mass?
no
Who came up with the current organization of the periodic table?
the same one who invented it
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.
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
Are families and groups the same in meaning in the periodic table of elements?
yes, families and groups the same meaning in the periodic table.
What are characteristics of periods in the periodic table?
Periods have same shells. There are 7 periods in periodic table.
When an atom becomes an ion does it affect its posistion in the periodic table?
No, absolutely not. The ion still has the same number of protons, which determines the element's position on the periodic table. The periodic table always stays the same.
What does family mean in the periodic table?
a family of the periodic table is like a group of elements of the same type.
What is the definition of block in periodic table?
In the periodic table elements having valence electrons in the same orbital are said to be placed in the same block.There are four blocks in the periodic table s, p, d and f.
Why there is a group of elements in periodic table?
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
Which other elements contain the same number of atomic shells as sodium?
All of the others in the same row of the Periodic Table as sodium.
What does the term periodic in periodic table refer?
The rows in periodic table are known as periods. The arrangement is such that elements with similar properties fall in the same period.
Where to find ions and atoms on the periodic table?
Not true I am trying to find the same thing out but I no for a fact they are both on a periodic table.
