The elements that are in the same row as each other all have their highest energy electron in the same principal electron shell. The first row (H and He) have valence electrons in the 1s orbital (the 1st shell only has a s-orbital). The second row has valence electrons in the 2s and 2p orbitals (the 2nd shell), and the third row has valence electrons in the 3s and 3p orbitals (the 3rd shell), etc.

This arrangement leads to so-called periodic trends in the Periodic Table.

What direction is a column in the periodic table?

A column in the periodic table is a vertical group of elements that share similar chemical properties due to having the same number of valence electrons. These columns are known as groups or families, and there are 18 groups in the periodic table.


What is a term for column on the periodic table?

Vertical columns are known as groups.


What is each vertical column in the periodic table?

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.


What are group on the periodic table?

In the periodic table a group is equivalent to a column.


What are the vertical columns on the periodic chart called?

The vertical column in a periodic table is called "The Group" and there are 8 groups in the periodic table, I through O or VIII.They are called Groups or sometimes Families. For many the periodic table has 8 groups but when you also include the transition metals, then there are 18 groups which gives you a better understanding when you are working out the electron arrangement within the atom's structure.
