Valency depends upon no of electrons in outer most shell the atoms have a specific no of electrons in valence shell so they have characteristic valence .(but transition metal violate this rule).
The number of valence shell electrons will generally determine the bonding characteristics of the element in question.
The valence of the element helium is 0.
Yes. Every element in a group has the same number of valence electrons.
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Boron has 3 valence electrons.Boron has 3 valence electrons.
The element with 6 valence electrons is carbon.
one valence electron
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
The periodic table can be used to quickly determine characteristics (number of valence electrons for example) of an element.
When determining an element's chemical properties, the most important subatomic particle to consider is the electron. Electrons, particularly those in the outermost energy level or valence shell, dictate how an element interacts with others, influencing its reactivity, bonding behavior, and overall chemical behavior. The arrangement and number of these valence electrons largely determine an element's position in the periodic table and its chemical characteristics.
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.
Valence electrons determine the reactivity of the element.
