The alkaline earth metals representthe second columnon the periodic table. Its six elements extend from beryllium (Be) to radium (Ra). These metals are named for forming basic solutions when put into water. They tend to form cations with a positive two charge and bond ionically. What are l...
In the Periodic Table application you will find a huge amount of data about chemical elements for free. You will learn a lot of new and useful for yourself, no…
Since the 19th century, the number of known elements has nearly doubled. Those newly discovered elements have slowly filled in the gaps on Mendeleev's original design and extended the table to even higher atomic numbers. All of the gaps were officially filled on the periodic table in the2010'...

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....
First, there is the cumbersome nature of a table on a cone, Secondly, see how the eight main group numbers at the top are sort of mushed into the 18 A and B series group numbers. This does not work well. The colour scheme shows the dominant acid-base properties of the elements: ...
(multiply by 4), sixth digits (multiply by 5) and so on for as many digits as there are. Now add all the numbers resulting from the multiplications together. Take the unit digit from this addition. It should match the last digit of the CAS registry numberr. If not, the CAS registry...
There are 18 groups in the standard periodic table. Elements in a group have similar configurations of their valence shell electrons, which gives them similar properties. Group numbers There are three systems of group numbers; one using Arabic numerals and the other two using Roman numerals. The...
Periodic Table of Elements - The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called groups and the horizontal rows are called peri
