Hydrogen - the intermolecular force occurring when a hydrogen atom is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule. Hydrogen bonds are usually represented by dotted lines connecting the hydrogen-bonded hydrogen to the unshared electron pair of the electronegative atom to which it’s attracted, proton gets attracted to unshared electron pair, strong with N, O, F Ex; NH3, hydrocarbon chain, 0, Ionic- a force that attracts electrons from one atom to another, which transforms a neutral atom into an ion Electrons are transferred from one atom to the other, found when electro negativity difference is greater than 1.7. Groups 1,2,17 mostly form ionic bonds

Unformatted text preview: Ex: salt, 1 Covalent- is the sharing of electrons between two atoms; atoms have electro negativity difference less than 1.7. Less than 0.3 is nonpolar covalent, a sigma bond is a type of covalent bond, they are the strongest type, there is a strong network, Ex: diamond, 2 Coordinate covalent-is a covalent bond between two atoms in which both electrons shared in the bond come from the same atom. They occur when a Lewis base donates a pair of electrons to a Lewis acid. Ex: carbon monoxide, 1+2 Metallic- bond formed by the attraction between positively charged metal ions and the sea of electrons around them, each atom can have one or more valence electron, and they can go to different atoms Ex: Cu, very strong...
