WHY is is what makes up an atom which makes up molecules which makes up us in the long run
Electrons are no reactive by itself but they are important in chemical reactions - valence electrons.
Valence electrons are important for the chemical reactions.
Electrons determine the chemical properties.
The electrons
When an atom undergoes chemical change, only the outermost (valence electrons) are involved.
the number of valence electrons determine the reactivity of the atoms
Its elemental weight
Electrons in the outermost energy level, known as valence electrons, are represented in Lewis notations. These electrons are important for determining the chemical reactivity and bonding capabilities of an atom.
Answer Electrons
Anything with electricity.
It creates current!
Both electrons and protons are equally important in any stable atom. The electrons give an atom its chemical properties, whereas protons enable us to identify an atom. It would be like asking what's more important on a football pitch: the football, or the players.
