Describe the reactivity of halogens
Valence electrons are the outermost electrons in an atom that are involved in chemical bonding. They determine the reactivity and chemical properties of an element.
The valence of the element helium is 0.
Boron has 3 valence electrons.Boron has 3 valence electrons.
The element with 6 valence electrons is carbon.
one valence electron
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.
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.
There are 2 valence electrons in cobalt.
