The elements in the same column have the same electrons in the outer shell.
Oh honey, I could go on for days about the periodic table! But to keep it short and sweet, the names on the periodic table are the elements. Each element has its own unique name like hydrogen, helium, oxygen, and so on. There are currently 118 elements on the periodic table, so buckle up, we've got a lot to cover!
groups
Elements in a row on the periodic table are called periods. They represent the number of electron shells an element's atoms have. Each period corresponds to the energy level of the electrons in an element's atoms.
On the periodic table, the family nitrogen belongs to is Group Vb. In their outer electronic shell, each of the elements within this group have five electrons.
Not families, Periods (Apex)
Each column is a group of chemical elements.
The elements are arranged in order according to the atomic number. The periodic table is arranged so that the elements in each column have similar chemical properties.
They're arranged so that the elements in each column have similar properties.
Each vertical column in the periodic table is called a group. Elements within the same group share similar chemical properties due to their similar electron configurations. There are 18 groups in the modern periodic table.
In the Mendeleev periodic table, elements in each column had similar chemical properties because they shared the same valence electron configuration. This allowed for elements within the same group to exhibit similar reactivity and form similar compounds.
All are different. Each element has its own row and column that it fits into.
The columns represent groups or families of elements. There are 18 of them.
There are 18 groups and 7 periods in the modern periodic table.
A "family" of elements means the vertical columns in the periodic table. If you look above the periodic table, there will be numbers for each row, numbered from 1 to 18. Each "family" is a column.
Periodic means repeating. When Mendeleev was rearranging the elements, he noticed that some of their properties matched with one another about every eight elements. Thus, when the elements are arranged in the rows of the Periodic Table, they also have matching properties in each column.
They change with atomic number.
Elements with the same number of valence electrons are in the same group (or vertical column).
