All elements a given column have the same number of valence electrons.
no, not all Greek architecture has columns
valency..
valency..
you list all the multiples of each number until you come to the first number that is in all columns
Groups! They all have same number of valence electrons in outer shell, which leads to similar chemical and physical characteristics.
It can depend on the style of the design. It is quite common though.
colums are called "families" or "groups". They are all placed in order according to the atomic number, and valend electrons
To Make all the columns the same length.
You can find Doric columns at many of the buildings that were made when the Doric order was the common architecture of the time. The most famous Doric columns would be found at the Parthenon temple.
The elements in the same vertical columns, also called groups or families, all share common traits with each other (for example, all of the alkali metals react violently when placed in water.) This is because all of the elements in one group contain the same number of valence electrons.
In space, the most common elements are?
Columns in an Excel table can be any width you like.
