The primary problem with ancient measurement systems was that there were a lot of different ones. No countries or nations as we know them today existed in ancient times, but there were numerous geographic areas that were generally under one rule, and most, if not all, of these areas had their own measurement system. Imagine the lack of communication that existed at that time, and even if one group of peoples did communicate with another group, imagine the timeliness of the communication compounded by the lack of a common language.

A first nation tribe is a blood kinship group. You don't 'join', you're not 'elected' and you don't pay dues or buy a uniform. You are born into a tribe, or you may be taken as a slave, adopted, arranged (political) marriage, won or lost in a gambling game...but it's not a Role Playing Game, this is Real Life.

newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
The periodic table is arranged in order (across and down the rows) in increasing number of protons in the nucleus; as the number of proton increases the radius of the nucleus generally increases - thus the order is the order reading down group 2: beryllium (least), magnesium, calcium, strontium, barium and radium (largest).
Computer Measurement Group was created in 1974.
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of Periodic Table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
Mendleef arranged the elements in the increasing order of their atomic masses due to which elements having same properties were placed in the same group and there were few exceptions.
This is a very wordy response, but by setting up the Periodic Table according to elements' properties and characteristics, he was able to predict any given elements' properties because, with the way the Periodic Table is arranged, all of the elements surrounding any specific element would have similar properties to the element that they surrounded. For example, at the time there was no element known as Aluminum, but given the properties of the elements around that area (Group 13), he was able to correctly predict Aluminum's properties. When aluminum was discovered, Mendeleev's predictions were extremely close to the actual element's properties.
The periodic law arranges the elements according to increasing atomic numbers and by lines depending on the number of electrons in the valence (outer) shell.
They are called desendents.

Flats are arranged in Blocks
well, basically the elements in the modern periodic table are arranged in the increasing order of atomic number. the elements are arranged in a group according to the valance electron. all elements in a group have same valance number of electron making the elements in group possess similar properties. further more as we go down the periodic table metalic character increases...
