Valency of nitrogen

The periodic table arranges the elements in a specific pattern based on their behavior.

Chlorine valency

Elements with the same number of valence electrons have the same properties. The groups are named by the element at the top of the column on the periodic table.

The Group 1A Lithium Family has 1 valence electron.

The atoms in this column of the periodic table tend to lose 1 electron, and this bonds it to an atom that prefers to accept 1 electron.

Elements in the Beryllium group have 2 valence electrons, and elements in the Oxygen group have 6.

In keeping with the pattern of elements wanting to have a full shell of electrons, oxygen group elements like to gain 2 electrons.

The Helium Family, also called the Noble Gases, are non-reactive because they have no openings in their outer electron shell.

The valency of elements such as iron that are in the metals family is more complex and can have different valencies, depending on the forces from the other atoms around it.

Some may have a valency of +2 under some circumstances and +3 under others. One of the reasons
