There is currently no scientific evidence for any constituents of an electron. So, for now, the electron is a lepton (a lepton is any fundamental particle).
Electrons, for chemical reactions
the electrons in the outermost shell of an atom are considered to be the valence electrons.
Electrons in the outermost shell are valence electrons!
Valence electrons
Lone-pair electrons, Bonded pairs of electrons
The electrons (especially the valence electrons)
8 electrons
The electrons farthest away from the nucleus are the valence electrons of an atom.
Chlorine has 17 electrons. 7 of its electrons are valence electrons.
N(nitrogen) = 7 electrons 3O(three oxygen) = 3* 8 electrons = 24 electrons 7 electrons + 24 electrons = 31 electrons in NO3 ( nitrogen trioxide ) ==============================
These electrons are called valence electrons.
