- Hydrogen bonds in water: (one or more may apply) Group of answer choices create surface tension in water are weak electrostatic bonds between 2 or more water molecules are covalent intramolecular bonds occurs because water molecules are polararrow_forwardThe “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)arrow_forwardWhich of the following statements is correct regarding polar/nonpolar molecules? 1. Molecules comprised of nonpolar covalent bonds are likely to be hydrophilic 2. Polar molecules like sugar tend to dissolve in solutions of other polar molecules like water 3. Nonpolar molecules like sugar tend to dissolve in solutions of polar molecules like water 4. Polar covalent bonds tend to form between molecules that consist of two atoms of the same element, like oxygen gas (O2) or nitrogen gas (N2)arrow_forward
