Hcn valence electrons.

Valence Electrons. In any given atom or element there are two types of electrons. There are the core electrons and the valence electrons. Electrons in the outer-most shell, called the valence shell, tend to react (be gained, lost, or shared) during a chemical reaction. You might imagine that, if two atoms bumped into each other, it would …
