Buckminsterfullerene, named for its discoverer, Buckminster Fuller.
English chemist John Newlands also attempted to classify the known elements of his day based on their atomic weight. Like de Chancourtois, he noticed a repeating pattern-every eighth element had similar properties.
Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.
Elements have different behaviour because of their electronic configuration.
The Periodic Table is arranged in periods and groups; elements are placed in the ascending order of the atomic number. The law of periodicity from Mendeleev is respected.
The periodic table is arranged in order by atomic number, the number of protons in the nucleus of the atom. The columns of the table represent elements with similar chemical characteristics. You could arrange the elements in alpha order, but it wouldn't be very useful.
In Mendeleev's periodic table the elements are arranged in increasing atomic mass and repeating properties whereas in in the modern periodic table the elements are arranged in increasing atomic number and repeating properties.

Groups are arranged as columns in the periodic table; the contained elements have similar properties.
The elements are arranged in the increasing order of their atomic number and repeating properties.
Brick repeat pattern is similar to Block, except instead of being perfectly aligned vertically and horizontally, the image layout is staggered, like a brick wall.
Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to atomic number.
In cyclical order. For example, if the sides of a hexagon are in three similar parts: a,a,b,b,c and c then rotational symmetry requires them to be in the order a-b-c-a-b-c (or similar). The angles also need to follow the same pattern.

The period of a function is a number where the function starts keep repeating its behavior. If a function has period of 300 days , for example, every 300 days the function keeps repeating its movement and behavior. This means 300,600,900 are all the start of a new period. This is somewhat similar to the seasons. The seasons have a period of 4 and they keep repeating their pattern every other 4 season.
English chemist John Newlands also attempted to classify the known elements of his day based on their atomic weight. Like de Chancourtois, he noticed a repeating pattern-every eighth element had similar properties.
The dream is not necessarily about the ex girlfriend, but refers to something she represents from 7 years ago. The dreamer might be repeating a pattern of behavior or making a mistake that was made in the past, related in some way to that ex girlfriend.
The modern periodic table is arranged in the increasing order of their atomic number and repeating properties. The elements in the same family / group have the same number of valence electrons.
