The valence is the outer most shell and im assuming you need the amount of electrons on the outer most shell which would be the valence electrons. There can be no more than 8. The rule is 2-8-8.
It could be done by referring to the group of that element in the periodic table.

To find the valency of an element, look at its group number on the Periodic Table. Elements in groups 1, 2, and 13-18 have valencies equal to their group number. For elements in groups 3-12, determine valency based on the number of electrons they need to gain or lose to achieve a stable electron configuration.

How do find valency number?
To find the valency number of an element, look at the group number on the periodic table. For main group elements (groups 1, 2, 13-18), the valency is the same as the group number. For transition metals, the valency can vary and is usually determined by the charge of the ion formed by the element.
What is the highest valency element?
The highest valency element is oxygen, with a valency of 2. The valency of an element represents the number of bonds it can form with other elements. Oxygen typically forms bonds by gaining two electrons to achieve a stable electron configuration.
Which element has 4 and 6 valency?
Carbon has a valency of 4, while sulfur has a valency of 6.
What is the valency of argon?
Argon is a noble gas and has a valency of 0. This means that it is stable and does not readily form chemical bonds with other elements.
What the valency of So2 and So3?
The valency of SO2 is 4, while the valency of SO3 is 6. The valency of an atom is the combining power of an element, which indicates the number of bonds it can form with other elements.
How do you find valency?
The valency of an element measures its ability to combine with other elements. This valency is determined by the number of electrons in the outer shell of each atom of an element.
What is the valency of the smallest element?
the smallest element is hydrogen of which its valency is one.
How do find valency number?

What is the highest valency element?
The highest valency element is oxygen, with a valency of 2. The valency of an element represents the number of bonds it can form with other elements. Oxygen typically forms bonds by gaining two electrons to achieve a stable electron configuration.
How do you find valency of elements?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
Which element has 4 and 6 valency?
Carbon has a valency of 4, while sulfur has a valency of 6.
What is the meaning of valency?
Valency (in chemistry) is the number of the valence bonds of a chemical element.
How calculate valency?
Valency is calculated in this way... 1. Find atm no of that element. 2. Write down electronic configuration. 3. Take the valence shell electron number. 4. The number of electrons to be lost are added as the valency.
What is bivalent ions?
an element which has valency 2
What is the valency of argon?
Argon is a noble gas and has a valency of 0. This means that it is stable and does not readily form chemical bonds with other elements.
What the valency of So2 and So3?
The valency of SO2 is 4, while the valency of SO3 is 6. The valency of an atom is the combining power of an element, which indicates the number of bonds it can form with other elements.
Which element has least valency?
The noble gases have the least valency which is zero. It is because thay have a complete shells.
