WebValence electrons are the electrons located in an atom's outermost shell. In helium's case, both its electrons will be valence electrons. Its electron configuration can be used to better show this He=1s 2 Two electrons in its outermost (and only) shell, two valence electrons. Was this answer helpful? 0 0 Similar questions WebThe total number of electrons in a valence shell is called valence electrons. The electron configuration shows that the last shell of arsenic has five electrons. Therefore, the valence electrons of arsenic are five.
