Group numbers The group number is an identifier used to describe the column of the standard periodic table in which the element appears. Groups 1-2 termed s-block elements. Groups 1-2 (except hydrogen) and 13-18 are termed main group elements....
Calcium, abbreviated as Ca on the periodic table, is a chemical element with the atomic number 20. It is a metallic element that belongs to Group 2 (or Group IIA) of the periodic table, which is also known as the alkaline earth metals. Calcium is a chemical element that is essential ...
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 ...

CAS system the letters A and B were designated to the main group elements and transition elements respectively. (The preparer of the table arbitrarily could use either an upper-or lower-case letter A or B, adding to the confusion.) Further, the old IUPAC system was more frequently used in...
Why is it called a periodic table? When Dmitri Mendeleev drew up the periodic table, he grouped elements of similar properties. Based on the number of electrons, a scientist can determine which group to place an element into.This pattern is called a period(or row) on the periodic table. ...
