The valence of an element is typically written as a positive or negative number to indicate the number of electrons gained or lost by an atom to attain a stable electron configuration. It can be determined based on the group number of the element on the Periodic Table for main group elements. Roman numerals in parentheses are sometimes used for transition metals to denote their variable valence states.

Valence electrons
How many valence electrons are in alkali metals?
one valence electrons
Does krypton have 8 valence electrons?
Yes, krypton has eight valence electrons.
What is the periodic trends in ionization energy?
The ionization energy increases because the energy required to remove a valence electron will increase. The atoms want to keep their valence electrons because as you move more towards the right of the Periodic Table towards the noble gases. To write an abbreviation for electron configuration, it requires a noble gas and the valence electron configuration.

How do you write the dot structure for argon?
Argon does not readily form chemical bonds with other atoms, so it does not have a dot structure like elements that participate in bonding. In dot structures, the symbol for the element is surrounded by dots representing its valence electrons. Since argon is a noble gas with a full valence shell, it is considered "stable" and does not form dot structures.
