Valency correct answers How many electrons the atom need to fill shell - Shell 1: 2e- - Shell 2: 8e- - Shell 3: 18e- Covalent bonds correct answers - Sharing of electrons between atoms of the same or different element Compound correct answers - combo of 2+ different elements Electronegativity correct answers - Atoms attraction for e- in covalent bond (EX: H2O) - Determines the distribution of e- w/in a covalent bond - higher value = stronger attraction of electrons EX: O = 3.5...

Explain the significance of the hydrogen bond correct answers •Similar to ionic bond but weak •Polarity causes water molecules to form weak (hydrogen) bonds between water molecules •Although the hydrogen bond between molecules is only 5% as strong as the bonds between hydrogen and oxygen (covalent bonds), it accounts for many of water's important properties •The way we see water today is almost a gel because of the hydrogen bonds Special properties of water (hydrogen bond is behin...
