All elements within a column are called a group.
This is probably a reference to the periodic table of the elements, which has columns. All the elements in a given column have the same configuration of valance electrons. There is a column of noble gases, a column of halogens, etc.
The electron configuration in the outer shell is the same for all of the elements in the same column. This results in some similar chemical properties between these elements in the same group (column).
They all are Halozen elements.
a family is a column of elements a period is a row of elements
Alkaline metals and hydrogen, all the elements in the first column of the Periodic Table.
Group 1 Elements (elements in the first group [column]) are classed as Alkali Metals. Group 2 Elements (elements in the second group [column]) are classed as Alkaline Earth Metals. All elements not in a representative group are classed as Transition Metals. Group 3 Elements (elements in the third full group [coulumn]) are classed as Earth Metals
That is correct; the first column on the left contains only elements with one electron in their outer shell, also known as "valance electrons". This column is referred to as Group 1, also known as the Alkali Metals.
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.
they have the same number of valence electrons
The elements in the 8 main columns of the Pperiodic Table are called Groups. Groups 1 and 2 are separated from Groups 3 to 8 by a block of elements called the Transition Series and the columns in this series have no specific names.
