Document Summary
Valence electrons are all the electrons after. Lewis dot structures show # of valence the noble gas in the abbreviation with the highest n (i. e. br has seven valence electrons [ar]4s 2 3d 10 4p 5 ) electrons. Each valence electron is represented by a dot around the element symbol. Octet rule represents a fully filled, stable configuration. Octet rule : an octet of 8 electrons (4 pair) Except for h and he for which the stable configuration is 2 electrons, the duet rule . Elements tend to gain, lose, or share electrons with other atoms, in order to complete their octet. Most main group elements will not allow more than 8 electrons to be assigned to them. Chemical bond : a net attractive force between two atoms which occurs due to the interactions of their valence electrons. There are two types of chemical bonds: are transferred from one atom to another.
