Valency is the charge of an ion or radical which has either lost or gained electrons
Note that metals lose electrons easily to become positive ions. This is why most metals are good conductors of electricity.
A Radical is a group of atoms usually charged which can keep itself intact and behaves like a unit in a chemical reaction.
For example:hydroxide ion (OH-) and ammonium ion (NH4+).
When A compound contains more than one such radicals then the formula of this is taken in brackets with their number written on the lower right hand side.

How can one determine the valence of an element in a chemical compound?
The valence of an element in a chemical compound can be determined by looking at the group number of the element on the periodic table. The group number indicates the number of valence electrons an element has. For example, elements in group 1 have a valence of 1, elements in group 2 have a valence of 2, and so on. The valence of an element is important in understanding how it will react with other elements to form compounds.
How can you determine the number of valence electrons for an element on the periodic table?
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.

Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
What type of properties do valence elcectrons determine for an element?
Valence electrons determine the reactivity of the element.
