one valence electron
An element is chemically active till it does not attain an inert gas configuration.
5 valence electrons.
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
its Atomic Mass.
Helium is stable with 2 valence electrons. It has a full outer electron shell, making it chemically inert and stable.
The element with 6 valence electrons is carbon.
Boron has 3 valence electrons.Boron has 3 valence electrons.
The number depends on what will fill the outer shell. It can be 2 or 8.
one valence electron
you have to give it 6 valence electrons
Valence electrons are the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determine the reactivity of an element. The number of valence electrons influences the element's properties and behavior in chemical reactions.
There are 8 valence electrons in the element Neon, as it is in group 18 of the periodic table.
An element is chemically active till it does not attain an inert gas configuration.
5 valence electrons.
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
