Question

Chemistry about Valence Electrons
Describe the activity of valence electrons (gain vs. Loss of electrons, including the scientific name for each) of metals vs non-metals and be sure to include reference to energy in your description of each activity.

Answer 1

valance electrons are the valance shell that is last shell electronics.......now every element wants to have the octet in valance shell....as it is considered as most stable state of the atom........now metals have either 1,2 or 3 electrons in their valance shell so to form octet it is easier for them to lose 1,2,or 3 electrons..so they metals lose them..and while losing they release the energy...........now in case of non metals..they have 5 or more than 5 electrons in their valance shell....so they tend to gain the electrons to form octet..for gaining they need energy so they absorb energy......

Answer 2

For this purpose they tend to form ionic(in bet metal and non metal..actual transfer of electron) or covenant bonds(non metal -non metal....share the valance shell electrons to complete octet)...
