This was the Russian chemist Dmitri Mendeleev.
If you mean the repeating pattern from left to right that occurs in the Periodic Table of the Elements, it is called the Law of Octaves. This is because the pattern of periodicity occurs in groups of eight.
There are eight groups that make up the main group elements. They are groups 1, 2, and 13 - 18. They are also called the representative elements.
Newland's octaves refer to the grouping of elements in the periodic table into groups of eight, based on similar chemical properties and electron configurations. This concept helps to predict the behavior of elements and their reactions in chemical reactions.
Not as written. Eight-hundred eighty-eight thousandths is eight thousandths greater than eighty-eight hundredths. The confusion comes from repeating decimals. 0.8 repeating is equal to 0.88 repeating is equal to 0.888 repeating.
The major mineral groups are silicates, carbonates, sulfates, halides, oxides, sulfides, native elements, and phosphates. These groups are classified based on the chemical composition and structure of the minerals.

Periodic means repeating. When Mendeleev was rearranging the elements, he noticed that some of their properties matched with one another about every eight elements. Thus, when the elements are arranged in the rows of the Periodic Table, they also have matching properties in each column.
The elements on the periodic table are arranged in order of increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement helps group elements with similar properties together in columns called groups or families. Additionally, elements are organized into rows called periods based on their electron configurations.
Groups on the periodic table are numbered from 1 to 18, with the group number corresponding to the number of valence electrons in the elements of that group. Group 1 elements have 1 valence electron, group 2 elements have 2 valence electrons, and so on. Groups 1, 2, and 13-18 are known as the main group elements.
