The purpose of this article is to discuss the work that led to the discovery of a periodic table of prime numbers based on their residue index. It was found that all of the prime numbers, beginning with 7, can be organized into eight categories or groups. The primes were grouped based ...
The periodic table of elements is a common sight in classrooms, campus hallways and libraries. The mode periodic table arranges the elements by their atomic numbers and periodic properties (周期性). Several scientists worked over a century to assemble the elements into this format. In 1789, Frenc...
This article lists five fool-proof methods to help you memorize the elements of the periodic table, their chemical symbols, and their atomic numbers. Whether you're studying for a periodic table quiz or just a chemistry enthusiast, these methods will hel
Electron Clouds The different layers of clouds hold different numbers of electrons 1st cloud = 2 2nd cloud = 8 3rd cloud = 8 These cloud layers conveniently match the rows on the periodic table: 1st row = 2 elements 2nd row = 8 elements 3rd row =8 elements… And then it gets ...
