The outermost electrons - Answer-valence electrons the shell the outermost electrons occupy - Answer-Valence shell Electron pairs in an electron dot structure that are not participating in a chemical bond - Answernon-bonding pair the electric force of attraction between two oppositely charged ions - Answer-ionic bond The fluid hold of electrons which holds the positively charged metal ions together - Answer-metallic bond An electrical attraction in which atoms are held together by their mu...

hydrogen bonding happens BETWEEN MOLECULES not within a single molecule hydrogen bonds are formed when two hydrogens are connected to the same element in multiple molecules when elements are sharing electrons which one has the more negative charge the one with the higher electronegativity hydrogen bonds form because the more electronegative element in one molecule attracts the less electronegative element in the other molecule what elements can make hydrogen bonds O, F, N
